Any of numerous and diverse fishes (suborder Blenniodei, order Perciformes) that are mostly small, marine species found from tropical to cold seas.

Blennies are slim, ranging from moderately elongated to very long and eel-like. Their habitats range from rocky pools to sandy beaches, reefs, and beds of kelp. Many live in shallow water, but some range to depths of about 1,500 ft (450 m). Some are mainly herbivores; others are partial or complete carnivores. They are generally unobtrusive and of little economic importance.

 any of the numerous and diverse fishes of the suborder Blennioidei (order Perciformes). Blennies are mostly small, usually marine fishes found from tropical to cold seas. They are slim, ranging in form from moderately elongated, as in some of the tropical species, to very long and eellike, as in the gunnel and wolffish (qq.v.) of northern waters. As a group, however, they are united by such features as a long dorsal fin and pelvic fins, when present, that are placed near the throat and contain one spine and two to four rays.

      The habitats of blennies range from rocky pools to sandy beaches, reefs, and beds of kelp. Many live in shallow water, but some range to depths of about 450 m (1,500 feet). Some are mainly herbivorous; the others are partially to wholly carnivorous. Blennies are generally unobtrusive, bottom-dwelling fishes. They are of little economic importance.

      Taxonomically, blennies comprise a number of families. The two largest are Clinidae, or clinids, with about 180 species, and Blenniidae, or blenniids, with about 300. The clinids, or scaled blennies, are carnivorous fishes, usually less than 30 cm (12 inches) long. They have a long, many-spined dorsal fin and usually a rather pointed nose. Many have fringed tentacles on their heads and snouts. The blenniids, or combtooth blennies, are small, blunt-nosed, scaleless blennies of warm and temperate seas. They have a single, sometimes notched, dorsal fin and slim, comblike teeth. The rockskipper (Istiblennius zebra) is a small Hawaiian blenny representative of several that live along shores and can hop about on land. The Hawaiian Runula goslinei and the Pacific R. tapeinosoma, both of which are small, are noted for nipping at swimmers.
