Hippoidea : ウィキペディア英語版
Hippoidea

Hippoidea is a superfamily of decapod crustaceans known as sand crabs, mole crabs, or sand fleas.〔(Sand Fleas (Mole Crabs or Sand Crabs) Prime surf fishing bait )〕〔http://www.baymoon.com/~ilga/crabs/ ''All About Mole Crabs''〕
==Ecology==
Hippoids are adapted to burrowing into sandy beaches, a habit they share with raninid crabs, and the parallel evolution of the two groups is striking. The whole body is almost ovoid, the first pereiopods have no claws, and the telson is long, none of which are seen in related groups. Unlike most other decapods, sand crabs cannot walk; instead, they use their legs to dig into the sand. Members of the family Hippidae beat their uropods to swim.〔
Apart from the polar regions, hippoids can be found on beaches throughout the world. Larvae of one species have also been found in Antarctic waters, despite the lack of suitable sandy beaches in the Antarctic.
