Fourhorn Sculpin
Myoxocephalus quadricornis
The fourhorn sculpin (Myoxocephalus quadricornis) is a species of fish in the Cottidae family. It is a demersal fish distributed mainly in brackish arctic coastal waters in Canada, Greenland, Russia, and Alaska, and also as a relict in the boreal Baltic Sea. There are also freshwater populations in the lakes of Norway, Sweden, Finland and Karelia (NW Russia) and in Arctic Canada (Nunavut and Northwest Territories).

Description
The fourhorn sculpin has a large knobbly head with protruding lips and four bony protuberances, though the latter are not present in freshwater, lake forms of this fish. The pectoral fins are large and rounded. Freshwater forms resemble the Alpine bullhead and European bullhead but can be distinguished from them by the fact that the dorsal and anal fins terminate further forward giving a greater length to the caudal peduncle. The head, body and fins are brownish, mottled and barred with darker colour. The belly of the male is yellowish-brown while that of the female is whitish. In the sea this fish reaches 20 to 30 cm (8 to 12 in) but in lakes it seldom exceeds 15 cm (6 in).
