(Cods) > Phycidae
Etymology: Urophycis: Greek, oura = tail + Greek, phyke, pykis, -idos = the female of a fish that lives among algae (Greek = phykon), related with the gudgeon (Ref. 45335).
Environment / Climate / Range
Marine; demersal; non-migratory; depth range 0 - 400 m (Ref. 57178). Subtropical; 38°N - 23°N, 98°W - 73°W (Ref. 56856)
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 35.0 cm TL male/unsexed; (Ref. 5232); common length : 25.0 cm TL male/unsexed; (Ref. 5232)
spines: 0. Upper limb of the first gill arch with two rakers. A series of dark spots present on the head; a dusky black blotch on the opercle. Lateral line alternately black and white (Ref 26938).
Western Central Atlantic: Beaufort, North Carolina south along the coast and into the Gulf of Mexico, where it occurs south off Mexico.
Found onshore but most common in less than 300 m. Shallow-water specimens feed on crustaceans, worms and fish. Moves into bays and coastal waters during colder weather (Ref. 26938). Minimum depth reported taken from Ref. 57178.
