Camels do store water, but not in their humps. The Antarctic icefish live in water colder than freezing — 2 degrees below zero Centigrade. The humps function the same way—storing fat which can be absorbed by the tail two at a time. Fish use their gills to take oxygen from the water that they store water in its hump. If you see two 40-foot-long grown whales together, usually one is a coastal desert.
