''Enophrys bison'', the buffalo sculpin, is a
species of marine
ray-finned fish, belonging to the
family Cottidae, the typical sculpins. It is found in the eastern Pacific Ocean.
Taxonomy
The buffalo sculpin was first formally described as ''Aspicottus bison'' in 1854 by the French zoologist Charles Frédéric Girard with its type locality given as San Francisco.

American bison (''Bison bison'').

pelvic fin
Pelvic fins or ventral fins are paired fins located on the ventral surface of fish. The paired pelvic fins are homologous to the hindlimbs of tetrapods.

This species is well-camouflaged and has a mottled pattern, which varies from pink and green to brown in colour, and there are dark saddle patches along the back. There is a long, straight preopercular spine projecting from each cheek. The

Distribution and habitat
This fish species occurs in the Eastern Pacific Ocean, from
Kodiak Island, Alaska, to
Monterey Bay, California, USA. They are typically found in rocky or sandy reef environments, where they can camouflage themselves in rocks and seaweed. These fish commonly inhabit a depths down to , though the deepest recorded depth is at .
Biology
Buffalo Sculpin are predators and prey on a variety of animals including young fishes, mussels, isopods, amphipods, and crabs. Algae are frequently recorded among its gut contents, but it is not clear that this is consumed deliberately or by accident when the fish grabs prey. It is an

fish in which there is paternal care. They spawn in the late winter through to early spring, the female laying her eggs on rocks or on artificial structures in the lower part of the
intertidal zone down as far as in depth. The eggs are laid in batches of 19,000 – 32,000 in exposed places, subject to the current. A number of females frequently spawn with a single male which then guards the eggs and fans them with his pectoral fins. The larvae emerge after 5 or 6 weeks. The

(''Asemichthys taylori'') lays its eggs on the egg masses of this species, thought to be a strategy to take advantage of the buffalo sculpin's egg guarding behaviour.
