Description

The wrymouth is an elongate, eel-like bottom fish of the family Cryptacanthodidae reaching about 97 cm. The naked, laterally compressed body has a continuous dorsal fin, small high-set eyes and an obliquely upturned mouth - hence the name wrymouth. The species lives in muddy bottoms of cold coastal water along the east coast of North America, where it digs extensive burrow systems and stays almost always hidden. From the burrows it ambushes small crustaceans, molluscs and worms. Because of its hidden, burrowing lifestyle it is only rarely seen and has no fishery value, though it sometimes comes up as bycatch.
