Leptograpsodes octodentatus, known as the burrowing shore crab,[4] is a species of crab in the superfamily Grapsoidea,[5] It is the only species in the genus Leptograpsodes,[2] and the family Leptograpsodidae.[3]
Description
[edit]It is up to 60 to 70 mm (2.4 to 2.8 in) across,[5][6] with an oval shaped carapace.[5] The species epithet octodentatus refers to four pairs of teeth (including the orbital angle) on the sides of the carapace,[4] although the fourth is very small.[7] Some references list one tooth only.[5] Color varies with the carapace described as grey and yellow, mottled green and brown, purple and yellow.[6] It can produce sound by stridulation.[6]
Sexual dimorphism
[edit]Adult males have large claws with curved fingers, with irregular teeth, whereas in females and juveniles the fingers are straight, with regular teeth.[4] These differences caused them to originally be given multiple species names.[citation needed]
Environment
[edit]It is typically found on southern Australian seashores in Victoria, Tasmania, South Australia and Western Australia (north to the Abrolhos islands),[4][6] and tends to live near fresh or brackish water,[4] but never far from the shore.[4] It lives in shallow burrows, above the high tide line, and comes out to feed at night, on rotting vegetation and animal debris.[4] Spawning is in summer from December to January.[4]
