About this species

Tetrosomus gibbosus, commonly called camel cowfish because of the hump on its dorsal keel, is one of 22 species in the boxfish family, Ostraciidae. It is a ray finned fish. Other common names include helmet cowfish, humpback turretfish and thornbacked boxfish. It is most closely related to T. reipublicae, the smallspine turretfish. T. gibbosus is a species of boxfish found in the wide Indo-West Pacific. It has been recorded since 1988 on rare occasions in the Levantine waters of the Mediterranean Sea, likely following entry via the Suez Canal. It is the first species from the family Ostraciidae to be found in the Mediterranean Sea.
