see text The Hemitripterinae is a subfamily of the scorpaeniform family Agonidae, known as sea ravens or sailfin sculpins.

They are bottom-dwelling fish that feed on small invertebrates, found in the northwest Atlantic and north Pacific Oceans.

The sea raven subfamily Hemitripterinae, was first proposed as a taxonomic grouping in 1872 by the American biologist Theodore Gill.

Their head and body are clothed with tiny "prickles", these being modified, platelike scales each having one spine which is covered in skin.

The gill membrane has a wide attachment to the isthmus and forms a fold across the throat.
