Genus Myxocephalus is a group of fish that is commonly referred to as sculpins. There are several synonyms for this genus, including Myoxocephalus, Cottus, and Triglops. These fish are found in the cold waters of the Northern Hemisphere, ranging from the Arctic to the North Pacific Ocean. Sculpins are characterized by their flattened heads, spiny fins, and bony plates. They are bottom-dwelling fish and are often found hiding in rocky crevices and kelp beds. Sculpins play an important role in the marine ecosystem, serving as both predator and prey. Their unique physiology and behavior make them fascinating subjects of study for marine biologists.
