Data about Siluriformes
About Data on EOL
TraitBank gathers data and metadata from multiple sources into a single, fully-referenced and semantically accessible taxon-centric view.
Contact us for more information on sharing data sets with EOL or to recommend a data set for inclusion into TraitBank.
Funding for the development of EOL computable data functionality provided by the Alfred P. Sloan Foundation, the John D. and Catherine T. MacArthur Foundation, and from EOL users around the world. Contact the EOL Secretariat for more information on TraitBank.

Glossary for Siluriformes
- An underground layer of water-bearing permeable rock or unconsolidated materials (gravel, sand, silt, or clay) from which groundwater can be usefully extracted using a water well.
- A branched quality inhering in a bearer by virtue of the bearer's being divided into two branches.
- From Phenotype and Trait Ontology
- body mass
- The amount of matter in the body of an organism.
- caudal fin shape
- Any measurable or observable characteristic related to the shape of a caudal fin.
- Naturally formed, subterranean open area or chamber.
- The physical confine of a river, slough or ocean strait consisting of a bed and banks.
- clutch/brood/litter size
- Single birth offspring quantity. The proportion or number of offspring produced from a single pregnancy (mammals) or ovulation (fish) or nesting (birds).
- coastal water body
- Coastal water is a marine water body bordering a coast.
- This taxon is still in existence, as opposed to extinct.
- extinction status
- Indicates whether a taxon is extant (living today) or extinct.
- first appearance (older bound)
- The older bound for the first appearance of this taxon in the fossil record, in Ma.
- first appearance (younger bound)
- The younger bound for the first appearance of this taxon in the fossil record, in Ma.
- fresh water
- A category or description of the habitat in which the Event occurred.
- last appearance (older bound)
- The older bound for the last appearance of this taxon in the fossil record, in Ma.
- last appearance (younger bound)
- The younger bound for the last appearance of this taxon in the fossil record, in Ma.
- The geographic latitude (in decimal degrees, using the spatial reference system given in geodeticDatum) of the geographic center of a Location. Positive values are north of the Equator, negative values are south of it. Legal values lie between -90 and 90, inclusive.
- The geographic longitude (in decimal degrees, using the spatial reference system given in geodeticDatum) of the geographic center of a Location. Positive values are east of the Greenwich Meridian, negative values are west of it. Legal values lie between -180 and 180, inclusive.
- marine biome
- An aquatic biome that comprises systems of open-ocean and unprotected coastal habitats, characterized by exposure to wave action, tidal fluctuation, and ocean currents as well as systems that largely resemble these. Water in the marine biome is generally within the salinity range of seawater: 30 to 38 ppt.
- marine habitat
- A habitat that is in or on a sea or ocean containing high concentrations of dissolved salts and other total dissolved solids (typically >35 grams dissolved salts per litre).
- million years ago
- 1 megaannum in the past. Megaannum, Ma. is a unit of time equal to one million (10^6) years.
- onset of fertility
- The age at which an organism develops the ability to produce live offspring.
- Natural freshwater surface streams of considerable volume and a permanent or seasonal flow, moving in a definite channel toward a sea, lake, or another river; any large streams, or ones larger than brooks or creeks, such as the trunk stream and larger branches of a drainage system.
- The part of an elevation or depression between the relatively flat surrounding area and the peak of a mount or the bottom of a depression.
- total life span
- The full period of time from birth to death of an organism.
- water depth
- The depth of seawater at a location where this organism has been observed or collected.
- water salinity
- Dissolved salt concentration in seawater at a location where this organism has been observed or collected.
- water temperature
- Temperature of the water at a location where this organism has been observed or collected.
- A physical quality inhering in a bearer that has mass near a gravitational body.
