The '''[[crocodile icefish]]''' or '''white-blooded fish''' (''Channichthyidae'') comprise a family of notothenioid fish found in the [[Southern Ocean]] around [[Antarctica]] and southern South America, where water temperatures remain relatively stable (generally ranging from -1.8 to +2.0 °C). Sixteen species of crocodile icefish are currently recognized. All icefish are believed to be piscivorous but can also feed on [[krill]]. Icefish are ambush predators; thus, they can survive long periods between feeding and often consume fish up to 50% of their own body length. Maximum body lengths of 25–50 cm have been recorded in these species.

To compensate for the loss of hemoglobin, they have larger blood vessels (including capillaries), greater blood volumes (four times that of other fish), bigger hearts, and greater cardiac outputs (fivefold greater) compared to other fish. Their hearts lack coronary arteries, and the ventricle muscles are very spongy, enabling them to absorb oxygen directly from the blood they pump.
At the age of 24, 'Cherry' was one of the youngest members of [[Robert Falcon Scott]]'s Terra Nova expedition (1910–13). This was Scott's second and last expedition to [[Antarctica]]. Cherry's application to join the expedition was initially rejected as Scott was looking for scientists, but he made a second application along with a promise of £1,000 (2009 approximation £50,000) towards the cost of the expedition. Rejected a second time, he made the donation regardless. Struck by this gesture, and at the same time persuaded by Dr Edward 'Bill' Wilson, Scott agreed to take Cherry-Garrard as assistant zoologist.

Apsley Cherry-Garrard was an English explorer of Antarctica. He was a member of the Terra Nova Expedition and is acclaimed for his historical account of this expedition, The Worst Journey in the World.

At the age of 24, 'Cherry' was one of the youngest members of Robert Falcon Scott's Terra Nova expedition (1910–13). This was Scott's second and last expedition to Antarctica. Cherry's application to join the expedition was initially rejected as Scott was looking for scientists, but he made a second application along with a promise of £1,000 (2009 approximation £50,000) towards the cost of the expedition. Rejected a second time, he made the donation regardless. Struck by this gesture, and at the same time persuaded by Dr Edward 'Bill' Wilson, Scott agreed to take Cherry-Garrard as assistant zoologist.
