Antarctic Ice Fish (image) Census of Marine Life Share Print E-Mail Caption As an adaptation to low temperatures, the Antarctic ice fish has no red blood pigments (haemoglobine) and no red blood cells. Thus the blood is more fluid and the animals save energy otherwise needed to pump blood through their body. Interestingly the brittle stars are overgrown by a yellow sponge.
