Remark
|
:
|
Also known as coconut crabs. Carapace relatively well calcified; eyestalk laterally flattened; eyes usually held subparallel to each other. Antennae laterally flattened. Coxae of third maxillipeds close to each other, without distinct gap between them. Chelipeds short, stocky, equal or unequal; when unequal, left chela larger. First 2 pairs of walking legs well developed, last 2 pairs reduced, third legs chelate. Abdomen bilaterally asymmetrical, not clearly divided into segments. Either hermit crabs or distinctly crab-like animals with abdomen tucked under carapace; uropods modified into a "rasp" used for clinging interior of gastropods shells (except in Birgus latro) (Ref. 343).
