context_page_description: The Tasmanian giant crab, Pseudocarcinus gigas is a very large species of crab that resides on rocky and muddy bottoms in the oceans off Southern Australia. It is the only species in the genus Pseudocarcinus.
context_section_description: The Tasmanian giant crab is one of the largest crabs in the world, reaching a mass of 17.6 kg (39 lb) and a carapace width of up to 46 cm (18 in). Among crabs only the Japanese spider crab (Macrocheira kaempferi) can weigh more. Male Tasmanian giant crabs reach more than twice the size of females, which do not exceed 7 kg (15 lb). Males have one normal-sized and one oversized claw (which can be longer than the carapace width), while both claws are normal-sized in the females. This crab is mainly whitish-yellow below and red above; the tips of the claws are black. Small individuals are yellowish-and-red spotted above.
