Description

Family Malacanthidae

Distribution: Atlantic, Indian, and Pacific. Depth range 10-500 m (usually 50-200 m). One species (Malacanthus latovittatus) may be found in both marine and brackish water (Goldie River , New Guinea).(Ref. 8991). One relatively long dorsal fin; total dorsal fin rays 22-64. Relatively long anal fin; 1 or 2 weak spines; soft rays 14-56. Top of head with or without cutaneous ridge . Operculum with one blunt or sharp spine. Branchiostegal rays 6. Truncate , double emarginate , emarginate to forked caudal fin . Vertebrae 24, 25, or 27 (precaudal 10 or 11). Larvae with elaborate spines (elongated and serrate) on the head and scale[1]. All species live in a burrow, some in a large rubble mound of their own construction, in pairs or colonies. They feed on benthic invertebrates or zoopankton. Assumed to be nonguarders (RF). Most aquarium specimens are collected with poison and soon die. According to Dooley 1978[1], the tilefishes are comprised of two morphologically different and evolutionary distinct groups and are distinct enough to be separate families [Branchiostegidae: with genera Branchiostegus, Lopholatilus, Caulolatilus and Malacanthidae: with genera Hoplolatilus and Malacanthus].The family Malacanthidae belongs to the Class Actinopterygii (ray-finned fishes ) and the Order Perciformes. It contains 5 genera and 40 species. It may be found in Marine and Brackish environments and is primarily Marine. Some members of this family are used in the aquarium trade. Reproductively, most members of this family are nonguarders. The main mode of swimming of adult fish in this family is subcarangiform. Compared with other fish, the activity level of this family tends to be normal. Members of this family have been dated back to the the Miocene epoch epoch. Etymology of this family name : Greek, mala = a lot of + Greek, akantha = thorn

Habitat

Inhabits patches of talus or rubble of steep outer reef slopes . Usually seen in pairs that quickly dive headfirst into their burrow when disturbed . Juveniles occasionally school with similarly colored juveniles of Pseudanthias pascalus.

Typically found in water with a depth of 0 to -1,204 meters (0 to -3,950 feet).[2]

Biome: Saltwater . Reef-associated .
