Lycozoarces regani is a small fish from the family of eel nuts (Zoarcidae) in the partial order of eel mother relatives (Zoarcales). It is a bottom-dwelling marine fish found in the northwestern Pacific in the Sea of ​​Okhotsk and in the Tatar Sound in the outer shelf region at depths of 50 to 300 meters. The species was named in honor of the British ichthyologist Charles Tate Regan .

features

Lycozoarces regani becomes 15 cm long and, compared to other eel nuts, has a relatively plump, laterally flattened and completely flaky body. The number of vertebrae is 65 to 71. All fins are spineless. The dorsal, anal and caudal fins have grown together to form a continuous fin edge. The caudal fin is supported by 13 to 15 rays and by two epuralia, elongated, free-standing bones in the caudal fin skeleton. The head is relatively large (approx. 20% of the standard length ), the lips fleshy. The eyes are surrounded by a semicircle of 5 to 6 suborbital bones. There are two pores between the eyes. Palatine teeth are present.

The species shows a clear sexual dimorphism with a significantly higher dorsal fin in the males. This has led to the fact that the male was originally described as the second species of the genus ( Lycozoarces hubbsi Popov, 1935 ).
