Triacanthidae

Triacanthidae is a family of marine fish belonging to the order Tetraodontiformes. They are commonly known as filefish or unicornfish due to their distinctive horn-like snout. Triacanthids are found in the Indo-Pacific region, with a few species occurring in the Atlantic Ocean. They inhabit coral reefs and rocky areas at depths ranging from 1 to 100 meters.

The family Triacanthidae consists of two genera: Triacanthus and Dendrochirus. Triacanthus includes the filefish, which are known for their elongated, file-like teeth. Dendrochirus comprises the unicornfish, characterized by their horn-like snout and large, fleshy lips.

Triacanthids are typically small to medium-sized fish, with some species reaching lengths of up to 30 centimeters. They have a compressed body shape and are usually gray or brown in color, with darker spots or stripes. Their diet consists mainly of crustaceans and other small invertebrates.

Triacanthidae is an important family in marine ecosystems due to their role in controlling crustacean populations. However, some species are also targeted by recreational and commercial fisheries. Conservation efforts are in place to protect these fish and their habitats.
