Any of about 300 species (family Cottidae) of inactive, bottom-dwelling fishes found principally in northern regions. Sculpins are slender and tapered and have one or more spines on the gill covers, large fanlike pectoral fins, and smooth or spiny skin. The head is usually wide and heavy. Most species live in shallow seawaters, some live in deeper waters, and others inhabit fresh water. The largest species grow to 2 ft (60 cm) long; the miller's-thumb (Cottus gobio), common in European lakes and rivers, is only about 4 in. (10 cm) long. Other species of Cottus are found in Asia and North America.

The easiest fishing method for Sculpin is a dropper loop setup with live or dead anchovies. Other good baits include squid and shrimp. Sculpin have also been caught on large plastic baits such as scampi and large grubs. Line size is not especially important as most Sculpin are caught in deeper water. Suitable hook sizes range from 1/0 to 3/0 Sculpin are not particularly fussy.
Sculpin stings are very painful and are often associated with swelling and reddening of the affected area. The most common treatment for a Sculpin sting is to submerge the stung area in warm to hot temperature water. The heat will help to denature the proteins in the poison and to relieve the pain of the sting. Sculpin are found in Fresh and Salt water. The freshwater ones are called "muddlers" or "Miller's Thumbs" and are often used as bait for Brown Trout and bass. Saltwater Staghorn Sculpins are used as bait for large Pacific Striped Bass. All but the Staghorn have large, sharp teeth, and some, like the large Sea raven, can inflict serious bites on people. Their venomous spines are on both dorsal fins, the pectoral fins, pelvic fins, anal fins, and several on the gill cover.
