Great sculpins are a species of fish belonging to the Cottidae family. This fish is considered to be the largest species of the genus Myoxocephalus, in terms of its weight and length. They inhabit the Bering Sea and the Washington coast of the North Pacific Ocean. They are also found in parts of Japan and Russia. These fishes reside in aquatic habitats comprising both saltwater and freshwater, unlike the mottled sculpin which is a closely related species that resides solely in freshwater. They are usually found on sandy or muddy surfaces, located at the bottom of the marine ecosystem.
The breeding season of these fishes occurs in January and February. Female fishes lay around 11,000 eggs which are fertilized externally through spawning. The young eventually hatch out of the eggs after successful fertilization. The males mature at five to six years of age, while the females mature at seven to eight years of age. The great sculpin (Myoxocephalus polyacanthocephalus) is Not Evaluated by the International Union for Conservation of Nature or IUCN Red List. However, the destruction of their habitat and climate change are a few of the major threats encountered by this species.

Great sculpins have a large body with a tapering end. They are considered to be the largest species of the genus Myoxocephalus. They have a large head with a patch of papillae forming bump-like structures. The fleshy papillae on the head are made up of modified scales. Their body consists of an olive-green coloration and their undersides are paler than the rest of the body. One unique characteristic of these fishes is the absence of scales. The coloration of this species might differ according to their habitat. Their cheeks have long spines protruding outwards and the pectoral fins located on their sides have a fan-shaped structure. The underside of the fins consists of sharp rays that help when gripping the surface. These fins primarily help them in their underwater movement. They do not have swim bladders.
