Butter Fish

Butter Fish, a name for Centronotus gunellus, a small fish of the Blenny family, common on the British coasts, and owing its popular name to the shiny secretion from the skin. Called also Gunnelfish, from the supposed resemblance of the compressed body to the gunwale of a boat. The name Butter-fish is given in New Zealand to Coridodax pullus, a large food-fish of the Wrasse family.
