; subclass Actinopterygii, order Perciformes)
A small family of marine fish that have a large head, a large, upward-directed mouth with fringed lips, and two dorsal fins. The anal fin is long and the pectorals well developed. Trichodon trichodon (Pacific sandfish), 31 cm, is thought to bury its body in the sand, awaiting the arrival of potential prey. Locally important as food fish, the two species of sandfish occur only in the N. Pacific basin.
