The Trichonotidae are a small family restricted to the Indo-west Pacific. Currently, one genus is recognised (Nelson 1994). Nine species are now known, of which three are recorded from Australia.
Sanddivers may either hover above sand or perch on sand adjacent to coral reefs or dive headfirst into sand. Some species, however, are known from silty to muddy bottoms. They have a distinctive elongate body and a strongly projecting lower jaw. Maximum size reached is 20 cm.
Originally, Nelson (1994) recognised six species and Randall & Tarr (1994) increased that to seven with the addition of a new species; Randall & Tarr also provided a key to species, as did Nelson (2001). Clark & Pohle (1996) described Trichonotus halstead from southern New Guinea, a species that may occur in Australia. It is not clear, however, whether it is distinct from T. blochii, a species known only from Australia. The family requires revision.
Nelson (1986) discussed features distinguishing the family from the Creediidae.
