Sculpins (Cottidae)
Sculpins are a large family with a worldwide distribution in marine and fresh waters. Sculpins have a flattened head, large frog-like mouth and eyes, a scaleless body, and large fan-shaped pectoral fins. They have two closely-spaced dorsal fins (one spiny, one soft), thoracic pelvic fins, a rounded tail fin and no anal spines. Two freshwater species exist in Connecticut, one native and one recently introduced.
