Regan's eelpout

Lycozoarces is distinguished from all the other eelpouts by having pelvic fins and a branchiostegal membrane which has a wide joint and creates a fold over the isthmus. They have a relatively robust body and tail, an interorbital pore, the caudal fin has 13 to 15 fin rays and the 5 or 6 suborbital bones form a semicircle around the eye. There are no fin spines and L. regani shows marked sexual dimorphism. The males have longer dorsal and anal fin rays, a longer upper jaw and are darker in colour. The maximum published standard length for L. regani is 15.2 cm (6.0 in).

Lycozoarces is found in the northwestern Pacific Ocean in the Sea of Okhtosk and the northern Sea of Japan. It is a demersal fish found at depths of between 50 and 300 m (160 and 980 ft).

Lycozoarces is likely a combination of Lycodes and Zoarces as this taxon shows features intermediate between those taxa, and the subfamilies named after then, Lycodinae and Zoarcinae. The specific name honours Charles Tate Regan, the English ichthyologist of the British Museum (Natural History), who in 1913 had described a number of Antarctic eelpouts.
