''Gecarcinus'' is the type genus of the land crab family Gecarcinidae. They are found in warmer coastal regions of the Americas, including islands in the Caribbean. Four species from oceanic islands were formerly included in ''Gecarcinus'' as the subgenus ''Johngarthia'', but are now treated as a separate genus, ''Johngarthia''. While all members of this genus are largely terrestrial, they have to return to the ocean to breed (the larvae are released into the sea). They are often colourful, with reddish, orange, purple, yellowish, whitish or blackish being the dominating hues. This has resulted in some species, notably ''G. quadratus'' and ''G. lateralis'', gaining a level of popularity in the pet-trade. ==Species== *''Gecarcinus lateralis'' (Fréminville, 1835) *''Gecarcinus quadratus'' (Saussure, 1853) *''Gecarcinus ruricola'' (Linnaeus, 1758) *''Gecarcinus nobilii'' Perger & Wall 2014 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gecarcinus」の詳細全文を読む スポンサード リンク
