Antarctic icefishes
43 species · 5 families
Antarctic icefishes are true survivors of the freezing Southern Ocean, with blood that does not freeze thanks to natural antifreeze proteins. In some species the blood is even colourless, as they have hardly any red blood cells — unique among vertebrates. They move slowly and economically in water near freezing, where few other fish can live. Many have a large head and sit on the bottom waiting for prey. It is a remarkable group that shows how extreme life can adapt.
