The Triangular boxfish (Tetrosomus concatenatus) is a saltwater fish of the family Ostraciidae that grows up to 30 cm.
Description
The triangular boxfish is a striking boxfish from the Indo-West Pacific, from East Africa to southern Japan and New Caledonia. The species grows to about 30 cm and has a hard, triangular bony carapace with a high dorsal ridge, in which only the fins, eyes and mouth move freely. Like other boxfishes it can release a toxin (ostracitoxin) into the water when stressed. As a slow bottom fish it searches soft bottoms and reefs for worms, small crustaceans and molluscs. The IUCN has not evaluated the species.
