Bathyal swimming crab

Last updated April 10, 2026

The bathyal swimming crab, Bathynectes longispina, is a species of crab in the family Polybiidae.^[2]^[1]

This species lives on seamounts and knolls,^[3] at depths as great as 600 metres (2,000 ft). It appears similar to other members of the portunid family, but has reduced swimming dactyls and long walking legs. As an adaptation to deep water, it has large eyes.^[4]
