Biology:Leptograpsodes
Leptograpsodes octodentatus, known as the burrowing shore crab,[1] is a species of crab in the superfamily Grapsoidea,[2] It is the only species in the genus Leptograpsodes,[3] and the family Leptograpsodidae.[4]
Description
It is up to 60 to 70 mm (2.4 to 2.8 in) across,[2][5] with an oval shaped carapace.[2] The species epithet octodentatus refers to four pairs of teeth (including the orbital angle) on the sides of the carapace,[1] although the fourth is very small.[6] Some references list one tooth only.[2] Color varies with the carapace described as grey and yellow, mottled green and brown, purple and yellow.[5] It can produce sound by stridulation.[5]
Sexual dimorphism
Adult males have large claws with curved fingers, with irregular teeth, whereas in females and juveniles the fingers are straight, with regular teeth.[1] These differences caused them to originally be given multiple species names.[citation needed]
Environment
It is typically found on southern Australian seashores in Victoria, Tasmania, South Australia and Western Australia (north to the Abrolhos islands),[1][5] and tends to live near fresh or brackish water,[1] but never far from the shore.[1] It lives in shallow burrows, above the high tide line, and comes out to feed at night, on rotting vegetation and animal debris.[1] Spawning is in summer from December to January.[1]
