Triacanthus

Triacanthus is a genus of marine ray-finned fish belonging to the family Triacanthidae, the triplespines or tripodfishes. The two species in this genus are found in the Indian Ocean and the western Pacific Ocean.

==Taxonomy== Triacanthus was first proposed as a monospecific genus in 1786 by the German naturalist Lorenz Oken with Balistes biaculeatus as its type species by monotypy. B. aculeatus was first formally described in 1786 by the German physician and naturalist Marcus Elieser Bloch with its type locality given as the Indian Ocean. In 1968, James C. Tyler classified the family Triacanthidae within the suborder Triacanthoidei alongside the Triacanthodidae. The 5th edition of Fishes of the World classifies the Triacanthoidei as suborder of the order Tetraodontiformes.
