Acropomatidae, also known as the Lanternbellies or the Temperate ocean-basses is a family of perciform fish consisting of 33 marine species. Members of Acropoma are notable for having light-emitting organs alongside their undersides. They are found in all temperate and tropical oceans, usually at depths of several hundred meters.
Members of the family are generally small, with some ranging up to 15.75 in (40 cm), but most no more than 5.91 in (15 cm). They have two dorsal fins, the first with 7-10 spines, and the second with possibly a spine in addition to 8-10 soft rays. The anal fin has 2-3 spines, and the pelvic fins one spine and five soft rays.
