Polybius henslowii : ウィキペディア英語版 | Polybius henslowii
''Polybius henslowii'' is a species of crab, the only species in the genus ''Polybius''. It is a capable swimmer and feeds in open water in the north-east Atlantic Ocean and western Mediterranean Sea. ==Description== The carapace of ''P. henslowii'' is almost circular, wide and long. The first pair of pereiopods (walking legs) carry claws, and the remaining four pairs are flattened with fringed edges.〔 This contrasts with other members of the family Portunidae, which have only the last pair of legs adapted for swimming.〔 ''P. henslowii'' is red-brown on the upper surface, and paler beneath.〔
