Triacanthoidei is a suborder of ray-finned fishes belonging to the order Tetraodontiformes, which includes the pufferfishes, triggerfishes and related taxa. These benthic fishes are mainly found in the Indian Ocean with some of the spikefishes found in the Western Atlantic Ocean.
Triacanthoidei was first proposed as a superfamily, the Triacanthoidea, in 1968 by the American ichthyologist James C. Tyler who placed it in the monotypic suborder Triacanthoidei.[1] The 5th edition of Fishes of the World does not use the superfamily classification for this taxon, listing only the suborder and its constituent families within the order Tetraodontiformes.[2]
Etymology
Triacanthoidei has its base in the name of the genus Triacanthus which prefixes acanthus, meaning "thorn" or "spine" with tri , which means "three". This is a reference too the large first spine of the dorsal fin and the two large spines in the pelvic fin.[3] The element oid is a contraction of oides which means "resembles".[4]

Triaconthoidei contains the following families:[2][5]
