What is "fourhorn sculpin"

n. A species of fish of the Cottidae family, (taxlink Myoxocephalus quadricornis species noshow=1), found in Canada, Finland, Greenland, Norway, Russia, Sweden, and the United States.

The fourhorn sculpin (Myoxocephalus quadricornis or Triglopsis 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).

The deepwater sculpin Myoxocephalus thompsonii of continental North American freshwater lakes (e.g., the Great Lakes) is closely related to the fourhorn sculpin and alternatively considered as a subspecies of the latter, Myoxocephalus quadricornis thompsonii.
