The fishes in this genus are known as turretfishes and they are found in the Indian and western Pacific Oceans.

These authorities argue that specimens from the Indo-Pacific be assigned to Tetrosomus reipublicae.

[2][3] The 5th edition of Fishes of the World classifies the genus Tetrosomus within the family Ostraciidae in the suborder Ostracioidea within the order Tetraodontiformes.

[5] Tetrosomus concatenatus has a maximum published total length of 30 cm (12 in).

This is a solitary species found in bays and estuaries with large isolted sponges, as well as in sea grass and seaweed beds in cosatal waters.
