FISH Fish are scaly, cold-blooded animals with fins that get their oxygen from the water using gills. Whales and other cetaceans have flippers. A floe is a sheet of floating ice, usually found in polar seas. A fluke is a single lobe of a whale's tail. Flukes have no bones and are all muscle.
Cetaceans swim by moving their flukes up and down in the water.
Fluking is when a whale raises its tail out of the water as it begins a dive. These are eaten by other carnivores. Fossils have been found on every continent on Earth.
