Majoidea Samouelle 1819

The Majoidea are a superfamily of crabs which includes the various spider crabs.

Taxonomy

In "A classification of living and fossil genera of decapod crustaceans" De Grave and colleagues divided Majoidea into six families:^[1]

• Family Epialtidae
  • Subfamily Epialtinae
  • Subfamily Pisinae
  • Subfamily Pliosomatinae
  • Subfamily Tychiinae
• Family Hymenosomatidae
• Family Inachidae
• Family Inachoididae
• Family Majidae
  • Subfamily Eurynolambrinae
  • Subfamily Majinae
  • Subfamily Micromaiinae
  • Subfamily Mithracinae
  • Subfamily Planoterginae
• Family Oregoniidae

The classification has since been revised, with subfamilies Epialtinae and Mithracinae being elevated to families and Hymenosomatidae being moved to its own superfamily. The family composition according to the World Register of Marine Species is as follows:^[2]

• family Epialtidae MacLeay, 1838
• family Inachidae MacLeay, 1838
• family Inachoididae Dana, 1851
• family Macrocheiridae Dana, 1851
• family Majidae Samouelle, 1819 – "true" spider crabs
• family Mithracidae Balss, 1929
• family Oregoniidae Garth, 1958
• family †Priscinachidae Breton, 2009

Notable species within the superfamily include:

• Japanese spider crab (Macrocheira kaempferi), the largest living species of crab, found on the bottom of the Pacific Ocean.
• Libinia emarginata, the portly spider crab, a species of crab found in estuarine habitats on the east coast of North America.
• Hyas, a genus of spider crabs, including the great spider crab (Hyas araneus), found in the Atlantic and the North Sea.
• Maja squinado, sometimes called the "European long leg crab or pie faced crab" because of the way its face is shaped.
• Australian majid spider crab, found off Tasmania, are known to pile up on each other, the faster-moving crabs clambering over the smaller, slower ones.^[3]

There is one fossil family, Priscinachidae, represented by a single species, Priscinachus elongatus, from the Cenomanian of France.^[4]

Les Majoidea (du latin majo, « mai », nom donné par Linné en raison de leur abondance saisonnière au mois de mai^[2]), sont une super-famille de crabes. Elle comprend plusieurs familles. Selon De Grave et Dean, depuis 2009 elle n'en compte plus que six, les familles Mithracidae, Pisidae et Tychidae sont considérées respectivement comme étant les sous-familles Mithracinae, Pisinae et Tychinae de la famille des Majidae^[3].

Ce sont des crabes à grandes pattes, d'où leur nom vernaculaire d'araignées de mer par analogie avec les araignées terrestres^[4].

蜘蛛蟹總科（學名：Majoidea）是甲殼亞門十足目的一個總科，包括多個俗稱為「蜘蛛蟹」的物種。本總科的物種體型較厚實而圓，足細長，行動遲緩。多數食腐肉。

分類

根據Grave (2009)年原來的文獻，蜘蛛蟹總科由五到六個科組成^[1]：

• 臥蜘蛛蟹科（Epialtidae（英语：Epialtidae））
• 膜殼蟹科（Hymenosomatidae）：有爭議，因為其形態特徵介乎蜘蛛蟹總科和關公蟹總科兩個物種之間。可能會被劃歸其他總科（例如：關公蟹總科）^[2]。WoRMS於2016年將這個科獨立出來，成立膜殼蟹總科^[3]。
• 尖頭蟹科（Inachidae）
• Inachoididae（英语：Inachoididae）
• 蜘蛛蟹科（Majidae）
• 突眼蟹科（Oregoniidae（英语：Oregoniidae））

豆眼蟹科（Pisidae（英语：Pisidae））和 Tychidae被分類到臥蜘蛛蟹科之下，成為了豆眼蟹亚科（Pisinae（英语：Pisinae））和Tychinae；而宝石蟹科（Mithracidae）則被分類到蜘蛛蟹科之下，成為了宝石蟹亚科（Mithracinae）^[1]。

而根據世界海洋物种目录（WoRMS），其分類如下：

• 臥蜘蛛蟹科（Epialtidae（英语：Epialtidae） MacLeay, 1838）
• 尖頭蟹科（Inachidae MacLeay, 1838）
• family Inachoididae（英语：Inachoididae） Dana, 1851）
• 蜘蛛蟹科（Majidae Samouelle, 1819）
• 宝石蟹科（Mithracidae Balss, 1929）^[1][4]：原為蜘蛛蟹科之下的一個亞科^[5]
• 突眼蟹科（Oregoniidae（英语：Oregoniidae） Garth, 1958）
• 豆眼蟹科（Pisidae（英语：Pisidae） Dana, 1851）

另外，Priscinachidae是蜘蛛蟹總科下的一個科，只有一個Priscinachus elongatus化石物種，發現於森诺曼阶^[6]。

常見物種

在蜘蛛蟹總科比較有名的物種包括有：

• 長喙大足蟹（Macropodia rostrata）：最小物種。
• 巨螯蟹（Macrocheira kaempferi）：其兩螯伸展時兩端相距逾4公尺（13呎），是最大的節肢動物，棲息於太平洋海底。
• 日本蜘蛛蟹（Maja japonica）
• Libinia emarginata（英语：Libinia emarginata）：見於北美洲東岸的河口。
• Hyas (genus)（英语：Hyas (genus)）, a genus of spider crabs, including the great spider crab（英语：great spider crab） (Hyas araneus), found in the Atlantic and the North Sea.
• 歐洲蜘蛛蟹（Maja squinado）
• Australian majid spider crab, found off Tasmania, are known to pile up on each other, the faster-moving crabs clambering over the smaller, slower ones.^[7]
• 磯蟹（Pugettia producta）：寬約1.25公分（0.5吋），長2.5公分（1吋）；背面綠紅兩色，下面綠色。
