Angulate Tortoise

Chersina angulata (Schweigger 1812)

Biology

provided by Arkive
The angulate tortoise feeds on a variety of angiosperms (flowering plants), as well as mosses, mushrooms, insects, snail shells and animal faeces (11). Activity patterns depend largely on temperature: on cool or wet days and in winter, the angulate tortoise is most active during the middle of the day, while in spring and summer it is less active during this hottest part of the day (12). Mating is most common between September and April. The male may pursue and bite at the legs and tail of the female during courtship (3) (4), as well as engaging in combat with rival males (3) (4) (5). When the time comes to nest, the female digs a hole, up to ten centimetres deep, into which usually only a single, oval-shaped egg is laid (3) (4) (13). Each female may potentially lay up to six times a year (13). The egg hatches after 4 to 14 months (4) (8), the new hatchling having a flattened shell a mere 4 centimetres long (3) (4). Reproductive maturity is not reached until about ten years of age (5).

Conservation

provided by Arkive
The angulate tortoise is listed on Appendix II of the Convention on International Trade in Endangered Species (CITES), meaning that international trade in angulate tortoises should be carefully monitored and controlled (1). Tortoises in South Africa and Namibia are protected wildlife, and permits are required for their collection or exportation (8). A number of conservation measures are being undertaken in the Cape Floristic Region, including the removal of alien plants and the expansion of protected areas (7). However, although around 14 percent of this unique region has some level of protection, these protected areas are not thought to be entirely representative of the region's biodiversity (7), and improved protection of the angulate tortoise's habitat may be required if the species is not to suffer declines in the future.

Description

provided by Arkive
A distinguishing feature of the angulate tortoise is its greatly enlarged 'gular scute', the frontmost part of its lower shell, under the head, which is used by the male as a weapon to ram and overturn other males when fighting for dominance (3) (4) (5). A small to medium-sized (3) and rather colourful tortoise (6), the angulate tortoise has an elongated, domed carapace (upper shell), which is yellowish brown to olive in colour. Wide dark borders and dark centres mark the scutes on the top of the carapace, and dark triangles decorate the seams of the scutes around its lower edge. The plastron, or lower shell, is yellow to reddish, with a wide black mark down the centre. The head is usually dark, often with yellow on top, the jaws are weakly serrated, and the upper jaw is hooked. The limbs are yellowish or brown and the toes bear strong claws (4). Male angulate tortoises are distinguished from females by being larger, and having a longer gular scute, longer tail, and concave plastron (3) (4) (6).

Range

provided by Arkive
The angulate tortoise is endemic to South Africa and southwestern Namibia. It is particularly abundant in parts of the Cape Floristic Region, and occurs at elevations of up to 900 metres or more (4) (7) (8). The species has also been introduced to Dassen Island, off the coast of South Africa (9), and further north at Swakopmund and Walvis Bay in Namibia (10).

Threats

provided by Arkive
The Cape Floristic Region is seriously threatened by a range of human activities which have greatly reduced the habitat of the angulate tortoise. Many areas have been extensively cultivated, forcing the angulate tortoise to survive in marginal areas of habitat which are often small and fragmented (7) (14). Even in upland areas where soils are less fertile, farming based on native crops, such as rooibos tea and cut flowers, is rapidly reducing the angulate tortoise's natural habitat, while dense stands of alien plants provide a further threat (7). Although the angulate tortoise is commonly kept as a pet (6), little information is available on wild trade in this species.

Tortuga ariet ( Catalan; Valencian )

provided by wikipedia CA

La tortuga ariet (Chersina angulata) és una espècie de tortuga de la família dels testudínids que es troba a les zones seques de matolls de Sud-àfrica. Aquesta tortuga és l'únic membre del gènere Chersina.

Morfologia

És una tortuga petita, tímida, amb una closca relativament variable. Sovint es poden distingir per les prominents protuberàncies del seu plastró a sota del cap. Aquestes són utilitzades pels mascles per lluitar pel territori o per les femelles.

Distribució

El seu hàbitat natural és la vegetació de matoll sec costaner de la part sud-occidental de Sud-àfrica. Aquesta àrea de distribució natural s'estén a través de la Regió Floral del Cap, tan al nord com al sud de Namíbia. A més, s'han introduït petites colònies pels turistes en els jardins domèstics a Swakopmund i Walvis Bay, més al nord al centre de Namíbia. També hi ha una colònia a l'Illa Dasse, enfront de les costes de Sud-àfrica.

Manteniment en captivitat

Aquesta tortuga és mantinguda com a mascota al jardí a Sud-àfrica. També és cada vegada més amenaçada per la recollida il·legal pel comerç de mascotes. Fora de la seva àrea de distribució natural i del seu clima en general no sobreviuen bé, així que quan s'exporten a l'estranger aquests animals solen morir. Això és en part perquè s'adapten al clima sec i càlid, de tipus mediterrani del sud d'Àfrica. També, naturalment, mengen una gran varietat de plantes indígenes de Sud-àfrica i, si es manté en un jardí, requereixen una gamma igualment àmplia de plantes disponibles per a alimentar-se. No van a mantenir-se saludables si s'alimenten només d'enciam.

Aquesta tortuga, com la majoria dels rèptils, també ha de ser capaç de regular la seva pròpia temperatura, movent-se entre els punts de sol i ombra. Si es manté com una mascota, per tant, necessita un gran jardí on es pot escalfar, així com buscar l'ombra quan sigui necessari. Es necessita un hàbitat sec, ja que la humitat constant és particularment dolenta per a ella.

Afrikanische Schnabelbrustschildkröte ( German )

provided by wikipedia DE
 src=
Farblich helleres Exemplar

Die Afrikanische Schnabelbrustschildkröte (Chersina angulata) ist eine Art aus der Familie der Landschildkröten und die einzige Art, die der Gattung Chersina zugerechnet wird. Sie ist in Südafrika und Namibia beheimatet.

Erscheinungsbild

Ausgewachsene Männchen der Afrikanischen Schnabelbrustschildkröte haben eine Carapaxlänge von 22,5 bis 28,5 Zentimeter. Weibchen bleiben deutlich kleiner und haben eine Carapaxlänge zwischen 18,5 und 22,5 Zentimeter. Die Art hat in der Regel 10 Randschilde. Der Bauchpanzer ist etwas länger als der Rückenpanzer, der verhältnismäßig lang und schmal ist.

Die Farbe des Rückenpanzers ist sehr variabel und reicht von einer hellen Hornfarbe über ein Gelblich-braun bis zu einem Oliv. Die einzelnen Wirbel- und Rückenschilde haben jeweils dunkle Ränder und eine dunkle Mitte, die sich deutlich von der helleren Schildmitte abhebt. Die Randschilde im vorderen Bereich und in der Körpermitte weisen dunkle Dreiecke auf einem hellen Untergrund auf. Der Bauchpanzer ist gelb bis gelb-rötlich.

Männchen lassen sich an dem konkaven Bauchpanzer und dem längeren und dickeren Schwanz von den Weibchen unterscheiden.

Verbreitung, Lebensraum und Lebensweise

Die Afrikanische Schnabelbrustschildkröte ist in Südafrika und Namibia beheimatet und kommt dort sowohl in Halbwüsten wie auch feuchteren Gebieten vor. Kennzeichnend für ihren Lebensraum sind heiße und trockene Sommer sowie kalte und durchaus regenreiche Winter. Die Afrikanische Schnabelbrustschildkröte bewohnt drei unterschiedliche Vegetationszonen. Die eine kennzeichnet sich durch einen Heide- und Grasbewuchs wie sie für den Süden und den Westen der Kapregion charakteristisch ist, Zonen mit Sukkulentenbewuchs sowie Dünendickichte mit immergrünen Bäumen und Sträuchern.

Die Afrikanische Schnabelschildkröte ist ganzjährig aktiv. Während langen regenreichen und kühlen Wintern nutzt sie jedoch auch selbstgegrabene Höhlen.[1] Sie ernährt sich überwiegend pflanzlich und ergänzt ihre Nahrung auch mit Schnecken. Sie frisst außerdem den Kot von Säugetieren. Das Gelege der Afrikanischen Schnabelschildkröte umfasst in der Regel nur ein Ei, in Ausnahmefällen auch zwei. Die Zeitdauer, bis aus dem Ei ein Jungtier schlüpft, ist abhängig von der Umgebungstemperatur und der Luftfeuchtigkeit. In der Regel vergehen zwischen Eiablage und Schlupf zwischen 90 und 125 Tage.

Angulate tortoise

provided by wikipedia EN

The angulate tortoise (Chersina angulata) is a species of tortoise found in dry areas and coastal scrub vegetation in South Africa. This tortoise is the only known member of the genus Chersina.

Name and taxonomy

This species is highly distinctive and is now classified by itself, in the monotypic Chersina genus. While it differs considerably from all other tortoise species, its closest relatives, according to phylogenetic studies, are the tiny "padloper" (Homopus) tortoise species, with which it shares its southern African habitat.[4]

Internationally it is known by the two names of "angulate" and "bowsprit" tortoise. Locally in southern Africa however, it is uniformly known as the "angulate" tortoise in English, and as the rooipens skilpad ("red-belly tortoise") in Afrikaans.

Description

A fully-grown specimen, in its natural fynbos scrub habitat.

Identification

A small, shy tortoise with a relatively variable shell, they can often be distinguished by their prominent "bowsprits", which are protrusions of the "gular" shields, from their plastrons under their chins. These are used by males to fight for territory or females. Uniquely, this species has only one gular shield under its chin; all other southern African tortoises have a divided/double scaled gular. Angulate specimens have five claws on their front legs and four on each back leg. They also, like most other southern African tortoises, have a nuchal scute.[5]

Regional variation

There is considerable regional variation in this species of tortoise. Angulates from the west coast of southern Africa tend to have a reddish colour, especially on the underside of their shell (from where their Afrikaans name of rooipens or "red-belly" comes). Inland specimens from the Karoo region are often darker, and some are known to be uniformly black. To the east of their range, individuals are typically smaller and have a lighter colour. Such tendencies can be diluted by admixture however, and in all populations individuals tend to assume a uniform brown colour in old age.[6]

Sexual dimorphism

This species shows considerable difference between male and female individuals. The male angulates tend to be larger, to have concave bellies, and to have a longer, thinner, "peanut" shape. They also have enlarged and extended gular scutes under their chins, which they use for sparring with each other. The females tend to be smaller and rounder, with a flat or slightly convex belly.

Natural range and threats

Distribution map of the angulate tortoise in South Africa and Namibia.

Their natural habitat is the fynbos, karoo, albany thickets and coastal scrub (strandveld) vegetation of the south-western part of South Africa. This is an area of semi-arid and Mediterranean climate, with winter rainfall. Within this climatic range however, the angulate tortoise is a tough and very adaptable species.

Geographically, this natural range extends across the Cape Floristic Region, as far north as the southern part of Namibia. In addition, small colonies have been introduced by tourists to domestic gardens in Swakopmund and Walvis Bay, even further north, in central Namibia. To the east, its range extends along the Cape's southern coast as far as East London. There is also an especially dense colony on Dassen Island, off the South African coast. Throughout its range, this tortoise usually occurs in the greatest numbers near the coast. Inland it occurs at lesser densities, though smaller populations are even found in parts of the Karoo.[7]

Within its natural range, the natural predators of the species include mongoose, jackals, badgers, baboons and predatory birds which attack the infants. Perhaps the largest killers of this species in its natural habitat are the periodic wildfires, which can kill hundreds of thousands at a time.[8][9]

Due to human activity, it is also increasingly threatened by habitat destruction from agriculture and other development, as well as illegal collecting for the pet trade and deaths from tortoises crossing busy roads. Human introduced species such as the pied crow kill thousands of infants every year, especially along the West Coast where this invasive species is rapidly spreading.[6]

Human interaction and captivity

Angulates are often spotted crossing rural roads and highways. Drivers may stop and assist them in crossing, but are prohibited by law from removing them from their natural area.

The angulate tortoise is commonly kept as a garden pet in South Africa. However the species is classified as "Protected Wild Animal" in the Nature Conservation Ordinance No. 19 (2000), and it is therefore strictly illegal to remove this animal from the wild. It may also not be transported, possessed, imported or exported without a permit.

A commonly reported problem is that, when a tortoise is spotted crossing rural roads, drivers tend to stop, pick it up and take it home - away from its habitat in the wild. This is illegal and traumatic for the tortoise. Instead drivers are encouraged to stop and, if they wish, assist it crossing the road in the direction that it was going.[10]

Nonetheless, there is a legal and regulated pet trade in this tortoise, especially for captive-bred specimens. However it is absolutely imperative to attain a permit when buying, selling or keeping this species.[6]

Diet

If kept in a garden, these tortoises need a sizable warm, sunny, dry, well-drained area, with a diverse range of possible plant foods.

They naturally eat a wide variety of indigenous South African plants and, if kept in a garden, they require a similarly wide range of edible plants available, on which to feed. They will not stay healthy if fed only one food type, such as lettuce.

Plants marked with * are most important to diet.

Grasses as for leopard tortoises:
Couch grass (Cynodon dactylon) Eastern Province vlei grass (Eragrostis lehmanniana) Dew grass (Eragrostis pseudo-obtusa) Bushman grass (Schmidtia kalahariensis) Carrot grass (Tragus racemosus) Beesgras (Urochloa pantcoides) Veld grass (Ehrhartacalycina) Darnel rye grass (Lolium temulentum) Barnyard grass (Echinochloa crus-galli) Mouse barley grass (Hordeum murinum) Crab finger grass (Digitaria sanguinalis) Dallas grass (Paspalum dilatatum) Wintergrass (Poa annua) Dropseed grass (Sporobolus africanus) Kikiyu grass (Pennisetum clandestinum) Buffalo grass (Stenotaphrum secondatum) Swazi grass (Digitaria swazilandensis) Alfalfa (Lucerne)

Weeds: (* are most important)
Plantago major (Broad leafed plantain)* Plantago lanceolata ( Buckhorn, narrow leafed plantain)* Taraxacum officinale (Dandelion most important)* Cnicus benedictus (Thistle) Galinsoga parviflora (Small flowered quickweed) Opuntia (most types)* Rubus cuneifolius (Sand bramble) Paperthorn Tribulis terrestris (common dubbeltjie)* Arctotheca calendula (Cape marigold) Trifolium repens (white clover) Note: becomes toxic when dry. Cerastium capensi (Cape chickweed)* Silybum marianum (Blessed milk thistle) Commelina benghalensis (indigenous wandering Jew)* Clover*

Unsuitable plants high in oxalates:
Sedum morganianum Sedum frutescens Aracea (arum lily) Amaranthus (pigweed) Begonia spp Oxalis spp Rheum rhabarbarum (rhubarb) Crassulae spp The Chenopodiacea family which includes beet greens, spinach and chard should be avoided as they contain oxalates.

Domestic dangers

Male angulate tortoises "jousting". Males are very territorial, fight each other at any opportunity, and should preferably not be kept together.

If the garden is suburban, then it should be securely walled, so that the tortoise does not wander into the nearby streets and traffic. The property should also not have a swimming pool, as angulate tortoises cannot swim (unlike many larger tortoise species), and will drown if it falls into deep water. Domestic dogs are a threat to captive tortoises, which are often badly injured or killed after being severely chewed on. If kept in groups, females never clash, however males are fiercely territorial and will fight each other at any opportunity. Males should therefore ideally be kept separately from other males.

Sun and temperature

This tortoise, like most reptiles, also needs to be able to regulate its own temperature, by moving between sunny and shady spots. It therefore needs a large garden where it can move about, so as to seek both natural sunlight, as well as shade, when necessary. It needs a dry habitat, as constant moisture is particularly bad for it.

Illegal trade and exports

Like many species of tortoises, the angulate is increasingly threatened by illegal collecting for the pet trade. When transported outside of their natural range and climate, these tortoises usually die. This is partly because they are adapted to the warm, dry, Mediterranean-type climate of the Cape, but also because they require a wide range of plant foods, which they typically do not receive when they are kept as pets by inexperienced keepers.

Internationally, the species is regulated by the CITES, or Convention on the International Trade in Endangered Species of Fauna and Flora (Appendix II), as well as other legislation on their international trade.[11]

Chersina angulata ( Spanish; Castilian )

provided by wikipedia ES

La tortuga angulada (Chersina angulata) es una especie de tortuga de la familia Testudinidae que se encuentra en las zonas secas de matorrales de Sudáfrica. Esta tortuga es el único miembro del género Chersina.

Morfología

Es una tortuga pequeña, tímida, con un caparazón relativamente variable. A menudo se pueden distinguir por sus prominentes protuberancias de su peto bajo la cabeza. Estos son utilizados por los machos para luchar por el territorio o por las hembras.

Distribución

Su hábitat natural es la vegetación de matorral seco costero de la parte sur-occidental de Sudáfrica. Esta área de distribución natural se extiende a través de la Región Floral del Cabo, tan al norte como al sur de Namibia. Además, se han introducido pequeñas colonias por los turistas en los jardines domésticos en Swakopmund y Walvis Bay, más al norte en el centro de Namibia. También hay una colonia en la Isla Dassen, frente a las costas de Sudáfrica.

Mantenimiento en cautividad

Esta tortuga es mantenida como mascota en el jardín en Sudáfrica. También es cada vez más amenazada por la recogida ilegal por el comercio de mascotas. Fuera de su área de distribución natural y de su clima por lo general no sobreviven bien, así que cuando se exportan al extranjero estos animales suelen morir. Esto es en parte porque se adaptan al clima seco y cálido, de tipo mediterráneo del sur de África. También, naturalmente, comen una gran variedad de plantas indígenas de Sudáfrica y, si se mantiene en un jardín, requieren una gama igualmente amplia de plantas disponibles para alimentarse. No van a mantenerse saludables si se alimentan solo de lechuga.

Esta tortuga, como la mayoría de los reptiles, también tiene que ser capaz de regular su propia temperatura, moviéndose entre los puntos de sol y sombra. Si se mantiene como una mascota, por lo tanto, necesita un gran jardín donde se puede calentarse, así como buscar la sombra cuando sea necesario. Se necesita un hábitat seco, ya que la humedad constante es particularmente mala para ella.

Chersina angulata ( Italian )

provided by wikipedia IT

La testuggine angulata (Chersina angulata Schweigger, 1812), unica specie del genere Chersina Gray, 1830, è una specie di tartaruga della famiglia dei Testudinidi[1].

Descrizione

Una caratteristica distintiva della testuggine angulata è lo «scuto gulare», vale a dire la parte più anteriore del piastrone, sotto la testa, straordinariamente ingrossato, che viene utilizzato dai maschi come arma per colpire e capovolgere i rivali durante gli scontri per la supremazia. Testuggine di dimensioni medio-piccole (i maschi possono raggiungere i 27,2 cm di lunghezza del carapace e i 2,1 kg di peso, le femmine i 21,6 cm di lunghezza del carapace e gli 1,8 kg), la testuggine angulata ha un carapace allungato e a forma di cupola, di colore variabile dal bruno-giallastro al verde oliva. Gli scuti della sommità del carapace presentano larghe bande scure ai margini e una regione centrale parimenti scura, mentre dei triangoli scuri decorano le saldature degli scuti attorno al margine inferiore. Il piastrone è di colore variabile dal giallo al rossastro, con un'ampia banda nera che ne attraversa il centro. La testa è generalmente scura, spesso con del giallo sulla sommità, le mascelle sono serrate debolmente e la mascella superiore è adunca. Gli arti sono giallastri o marroni e le dita sono munite di robuste unghie. I maschi di testuggine angulata si distinguono dalle femmine, oltre che per le maggiori dimensioni, per il fatto di avere uno scuto gulare più lungo, una coda più lunga e un piastrone concavo[2].

Biologia

La testuggine angulata si nutre di una grande varietà di angiosperme (piante con fiori), così come di muschi, funghi, insetti, conchiglie di lumache e feci di animali. Il periodo di attività dipende in gran parte dalla temperatura: nelle giornate fresche o umide e in inverno, la testuggine angulata è più attiva nelle ore centrali della giornata, mentre in primavera e in estate è meno attiva durante questa parte più calda del giorno. L'accoppiamento in genere si verifica tra settembre e aprile. Durante il corteggiamento il maschio può inseguire e mordere le zampe e la coda della femmina, nonché ingaggiare combattimenti con i maschi rivali. Quando si approssima l'epoca della deposizione delle uova, la femmina scava una cavità, profonda fino a dieci centimetri, in cui depone generalmente un unico uovo di forma ovale. Ogni femmina è potenzialmente in grado di deporre fino a sei volte l'anno. L'uovo si schiude dopo un periodo che varia tra i 4 e i 14 mesi e il neonato possiede un carapace appiattito lungo appena 4 cm. La maturità sessuale viene raggiunta solamente verso i dieci anni di età[2].

Distribuzione e habitat

La testuggine angulata è endemica del Sudafrica e delle regioni sud-occidentali della Namibia. È particolarmente numerosa in alcune parti della Regione floristica del Capo ed è presente fino a 900 m o più di altitudine. La specie è stata introdotta anche su Dassen Island, al largo delle coste del Sudafrica, e più a nord, a Swakopmund e Walvis Bay, in Namibia. Abita una grande varietà di habitat, tra cui il fynbos, il Karoo succulento, il Karoo nama e la macchia di Albany[2].

Conservazione

La Regione floristica del Capo è seriamente minacciata da tutta una serie di attività antropiche che hanno grandemente ridotto l'habitat della testuggine angulata. Molte aree sono state convertite in terreni agricoli e la specie è costretta a sopravvivere in zone marginali di habitat che sono spesso piccole e frammentate. Perfino nelle regioni più elevate, dove il suolo è meno fertile, l'agricoltura basata sulla coltivazione di colture autoctone, come il tè rooibos e i fiori da taglio, ha ridotto rapidamente l'habitat naturale della testuggine angulata, mentre i fitti boschetti di piante aliene costituiscono un'ulteriore minaccia. Nonostante la testuggine angulata venga tenuta comunemente come animale domestico, le informazioni riguardanti il commercio di esemplari selvatici di questa specie sono scarse[2].

La testuggine angulata è inserita nell'Appendice II della Convenzione sul commercio internazionale delle specie minacciate di estinzione (CITES), il che significa che è possibile un limitato e controllato commercio internazionale. Tutte le testuggini di Sudafrica e Namibia sono protette dalla legge e per la loro raccolta o esportazione sono necessari appositi permessi. Un certo numero di misure di conservazione sono state avviate nella Regione floristica del Capo, compresa la rimozione delle piante aliene e l'espansione delle aree protette. Tuttavia, sebbene circa il 14% di questa regione unica goda di un qualche livello di protezione, si ritiene che le aree protette esistenti non siano rappresentative dell'intera biodiversità della regione e per evitare che la specie vada incontro ad un futuro declino è necessario aumentare la protezione dell'habitat nel quale essa vive[2].

Snavelborstlandschildpad ( Dutch; Flemish )

provided by wikipedia NL

Herpetologie

De snavelborstlandschildpad[2] (Chersina angulata) is een schildpad uit de familie landschildpadden (Testudinidae).

Naam

De soort werd voor het eerst wetenschappelijk beschreven door August Friedrich Schweigger in 1812. Oorspronkelijk werd de wetenschappelijke naam Testudo angulata gebruikt. Het is de enige soort uit het monotypische geslacht Chersina. De soort behoorde lange tijd tot het geslacht Testudo, waardoor de verouderde wetenschappelijke naam in de literatuur wordt gebruikt.[3] De soortnaam angulata betekent 'schuin'.

Uiterlijke kenmerken

De schildlengte is maximaal 30 centimeter.[4] De snavelborstschildpad dankt zijn naam aan een verlengsel van het buikschild in de vorm van een punt onder de kop dat alleen het mannetje heeft. Hierdoor lijkt de schildpad een enorme opengesperde bek te hebben, maar dit uitsteeksel is bedoeld om concurrenten mee weg te duwen in de strijd om een vrouwtje. De dieren hebben meestal zwarte of donkerbruine schildplaten met in iedere plaat op de rug een rode of gele vlek en een schildrand met een motief dat doet denken aan de 'haaientanden' als wegmarkering, hoewel variaties voorkomen. De schildrand is meestal geel van kleur. De ogen hebben een oranje of rode kleur.

Leefwijze

Het voedsel bestaat uit plantendelen zoals bladeren en fruit. Ook is beschreven dat slakken worden gegeten.

Verspreiding en leefgebied

Deze landschildpad komt voor in droge streken en leeft in het zuidwesten en zuiden van Afrika, in droge steppen en half-woestijnen.

Chersina angulata ( Portuguese )

provided by wikipedia PT

Chersina angulata é uma espécie de tartaruga encontrada em áreas secas e vegetação matagal costeira na África do Sul. Esta tartaruga faz parte do único conhecido membro do gênero 'Chersina' .

Nome e taxonomia

Esta espécie é altamente distinta e agora é classificada por si mesma, no monotípico gênero Chersina. Embora difira consideravelmente de todas as outras espécies de tartaruga, seus parentes mais próximos, de acordo com estudos filogenéticos, são as minúsculas espécies de tartaruga "Homopus]", com as quais compartilha o habitar da África Austral.[1]

Internacionalmente é conhecido pelos dois nomes de tartaruga "angulada" e "gurupés". No entanto, localmente na África do Sul, ela é uniformemente conhecida como a tartaruga "angulada" em inglês e como rooipens skilpad ("tartaruga de barriga vermelha") em Afrikaans.

Descrição

 src=
Um espécime totalmente crescido, em seu habitat natural de matagal fynbos.

Identificação

Uma tartaruga pequena e tímida com uma carapaça relativamente variável, eles podem frequentemente ser distinguidos por seus "gurupés proeminentes", que são protuberâncias dos escudos "gulares", de seus plastrões s sob o queixo. Eles são usados ​​por homens para lutar por território ou por mulheres. Excepcionalmente, esta espécie tem apenas um escudo gular sob o queixo; todas as outras tartarugas da África Austral têm uma gular dividida / dupla escala. Os espécimes angulados têm cinco garras nas patas dianteiras e quatro em cada uma das patas traseiras. Eles também, como a maioria das outras tartarugas da África Austral, têm um escudo nucal.[2]

Variação regional

Há uma variação regional considerável nesta espécie de tartaruga. Os angulados da costa oeste do sul da África tendem a ter uma cor avermelhada, especialmente na parte inferior de sua concha (de onde vem seu nome em Afrikaans de rooipens ou "barriga vermelha"). Espécimes do interior da região Karoo são geralmente mais escuros, e alguns são conhecidos por serem uniformemente pretos. Ao leste de sua distribuição, os indivíduos são geralmente menores e têm uma cor mais clara. Essas tendências podem ser diluídas pela mistura, entretanto, e em todas as populações os indivíduos tendem a assumir uma cor marrom uniforme na velhice.[3]

Perigos domésticos

Se o jardim for suburbano, ele deve ser bem murado, para que a tartaruga não perambule pelas ruas próximas e pelo tráfego. propriedade também não deve ter piscina, pois as tartarugas anguladas não podem nadar (ao contrário de muitas espécies de tartarugas maiores) e irão se afogar se cair em águas profundas. Os cães domésticos são uma ameaça para as tartarugas em cativeiro, que costumam ser gravemente feridas ou mortas após serem severamente mastigadas. Se mantidos em grupos, as fêmeas nunca entram em conflito, porém os machos são ferozmente territoriais e lutarão entre si em qualquer oportunidade. Os machos devem, portanto, ser mantidos separados de outros machos.

Черепаха кутоподібна ( Ukrainian )

provided by wikipedia UK

Опис

Загальна довжина коливається від 16 до 22 см. Спостерігається статевий диморфізм: самці більші за самиць. Голова невелика, товста. Карапакс куполоподібний, подовжений. Пластрон складається з 12 щитків. Єдиний горловий щиток сильно виступає уперед.

Карапакс червонувато—коричневого або коричневого—чорного кольору. Пластини всередині чорні, облямовані жовтим або червоно—помаранчевим кільцем.

Спосіб життя

Полюбляє берегові ділянки з сухою травою та чагарниками. Активна вранці. Харчується фруктами, овочами, рослинами, дрібними равликами. Черепаха може поїдати свій і чужий кал.

Шлюбний сезон протікає з вересня до січня. Самці в цей час стають неспокійними і взаємно агресивними. Самці можуть кусати самиць за лапи. Самиця відкладає 1 яйце, рідко 2, розміром 30×42 мм й вагою 20—25г. Кладок за сезон може бути кілька (інтервал 28—45 днів). Інкубаційний період триває 94—198 днів при температурі 26—28 °C. При більш низьких температурах термін інкубації подовжується. Новонароджені черепашата мають довжину 35 мм й вагу 14 г.

Розповсюдження

Мешкає у Капській провінції від Іст—Лондону на захід аж до гирла р. Оранжевої (Південно-Африканська Республіка). Наразі намагаються поширити цю черепаху у Намібії.

二名法 C. angulata
(Schweigger, 1812年)

挺胸龜(學名:Chersina angulata)是一種生於南非乾地及灌木林的陸龜。曾有遊客將小量挺胸龜帶回納米比亞並於私人花園中飼養。

特徵

挺胸龜為一種害羞的龜種,而牠們的背甲極為凸出,同時牠們底甲近下巴的位置凸起。這些都是用來爭取領土或雌性的雄性的特徵。

自然生長環境

它們的自然棲息地位於南非西南部,為高山中的硬葉灌木群落,卡魯和沿海灌木植被的部分。這種天然的生境延伸至弗洛勒爾角,大概為納米比亞北部的南面部分。此外,小數龜隻亦在過往遷移至斯瓦科普蒙德華維斯灣,更有部分遷移至納米比亞北部,而Dassen Island亦有小數挺胸龜出現。

ソリガメ(橇亀、学名Chersina angulata)は、リクガメ科ソリガメ属に分類されるカメ。本種のみでソリガメ属を形成する。

分布[編集]

南アフリカ共和国南部から南西部固有種

形態[編集]

最大甲長30cmだがこの個体の性別は不明。オスの最大甲長は27.2cm。メスよりもオスの方が大型になり、メスは最大でも21.6cm。背甲はドーム状に盛りあがり、上から見ると細長い。縁甲板は鋸状にならず滑らかで、やや反り上がる。左右の第12縁甲板は癒合する。肋甲板や椎甲板の色彩は孵化直後からある甲板(初生甲板)が暗褐色で、その周囲が黄褐色、甲板の外縁が暗褐色に縁取られる。縁甲板の色彩は黄褐色で、甲板ごとに1つずつ三角形の暗色斑が入る。しかし老齢個体では背甲が暗褐色一色になったり、椎甲板や肋甲板の初生甲板を除いて黄褐色になる個体もいる。左右の喉甲板は癒合し、骨甲板も含めて前方に突出する。種小名angulataは「角のある、角張った」の意で、突出した喉甲板に由来し英名(angulated)と同義。和名は喉甲板がソリのように見えることが由来。また英名bowsprit(バウスプリット)も突出した喉甲板に由来する。

頭部は小型。頭部の色彩は黄褐色で、頭頂部は黒や暗褐色。四肢は頑丈で、指趾には発達した爪が生える。

卵は長径3.4-4.3cm、短径2.4-5.3cmで白く硬い殻で覆われる。幼体の背甲は上から見ると円形だが、成長に伴い細長くなる。

オスは背甲がより細長く、喉甲板の突出が顕著。またオスは尾が太くて長い。

分類[編集]

核DNAおよびミトコンドリアDNA塩基配列解析による分子系統学の研究では、同じアフリカ大陸に分布するヒョウモンガメ属ヒラセリクガメ属ヤブガメ属に近縁で単系統群を形成すると考えられている。

生態[編集]

標高900m以下の森林や半砂漠地帯などに生息する。昼行性。周年活動するが、冬季に気温の低い日には落ち葉の下などで活動せずに過ごす。

食性は植物食で、主にを食べるが陸棲の貝類を食べることもある。

繁殖形態は卵生。オスは繁殖期になると互いに体当たりをしたり、突出した喉甲板で相手をひっくり返して争う。オスはメスを追いかけ後肢や尾に噛みつき交尾を迫る。1回に1個(2個産むこともある)の卵を産む。卵は180日以上、時に12-14か月かけて孵化する(飼育下では94-198日で孵化した例がある)。

人間との関係[編集]

開発による生息地の破壊、野火、ペット用の採集(密猟)などにより生息数は減少している。しかし生息地の大部分が自然保護区に指定されているため、絶滅の危険性は低いと考えられている。

ペットとして輸入されることもあり、日本にも輸入されている。流通はまれ。飼育下では人工飼料にも餌付く。
