Members of the family are generally small, with some ranging up to 40 cm, but most no more than 15 cm. They have two dorsal fins, the first with seven to 10 spines and the second with possibly a spine in addition to eight to 10 soft rays. The anal fin has two or three spines, and the pelvic fins one spine and five soft rays.
