Fish Types | Icefish | The crocodile icefish or white-blooded fish (Channichthyidae) are a family of perciform fish found in the cold waters around Antarctica and southern South America. Water temperature can drop to -1.9 °C (the freezing point of seawater) in the Antarctic sea but stays rather constant. There are about 25 currently recognized species of crocodile icefish. They feed on krill, copepods, and other fish. Icefish reach total length of 25-75 cm. Their blood is yellow because it contains no hemoglobin. Red blood cells are usually absent and if present are rare and defunct.
