Symphysanodon

Symphysanodon typus

The slope fish ( Symphysanodon ) ( symphysis Gr. An = without, Odous = tooth ) are a genus of related bass fish that occurs with ten species in the western Atlantic and Indo-Pacific at depths of 90-500 meters. It is the only genus of the order monotypic family Symphysanodontidae, their systematic position within the perch family is uncertain. Hang fish are poorly understood. Some species are known only by the holotype, only a reference or only by finds from predator stomachs.

Features

Hang fish are small fish that resemble externally the anthias ( Anthiinae ) and reach a length of 8 to 20 inches. Characteristic of the family are two spines on the gill cover. Their dorsal fin is normally supported by nine hard and ten soft rays.
