Thornfish

Bovichtus variegatus

The icefish ( Bovichtidae ) live in cold and temperate waters of the southern hemisphere on the border of the Southern Ocean, in the seas around New Zealand, southern Australia and southern South America. In addition, in freshwater Southeastern Australia and Tasmania.

Features

The fish are 9-80 inches long. Your mouth is vorstreckbar, the muzzle not very long. You have a single lateral line organ. The fish have two dorsal fins, a hard and a weichstrahlige. Vomer and palatine bones are dentate. The icefish have an effective antifreeze in their bodies and are therefore the only fish that can survive in cold water below zero degrees. Normally fish freeze to death at a water temperature of -1.95 ° Celsius.
