A small family of temperate fishes, closely related to morwongs (Cheilodactylidae), known only from Australia, Lord Howe Island, New Zealand, Chile and the Juan Fernandez Islands. The family contains a single genus with 6 species.
Species have nostrils tubular with tufts of cirri; scales cycloid, of moderate size; a single, long based dorsal fin with stout spines, spinous section separated by distinct notch from slightly shorter-based soft portion; anal fin small with strong spines; pectoral fins large with branched rays dorsally and 6 distinctly thicker, simple, unbranched rays below, lower rays extending well beyond edge of membrane and some beyond tips of branched rays; pelvic fins small.
Kelpfishes are well adapted for life in shallow coastal waters where they are exposed to strong wave action. They use their large pectoral fins to lodge their bodies into small depressions or cracks in rocks to hold themselves in place against the surge.
