Triacanthidae

Triacanthidae, (from Ancient Greek τρι- (tri-), meaning "three", and ἄκανθα (ákantha), meaning "spine") known as the triplespines or tripodfishes, is a family of marine ray-finned fishes belonging to the order Tetraodontiformes, which also includes the pufferfishes, boxfishes, filefishes and related groups. The family is made up of four extant genera and three extinct genera which are known from fossils.

==Taxonomy== Triacanthidae was first proposed as a family in 1859 by the Dutch physician, herpetologist and ichthyologist Pieter Bleeker, and, in 1968, James C. Tyler classified it within the suborder Triacanthoidei alongside the Triacanthodidae. The 5th edition of Fishes of the World classifies this as suborder of the order Tetraodontiformes.
