Fish have bones and are cold-blooded. (Cold-blooded means that their body temperature depends on the temperature of the water around them, unlike humans, who have a normal body temperature that stays at 98.6 degrees.) They breathe oxygen from the water through gills on the sides of their bodies. They cannot breathe air or live outside of water. Most fish are covered with small scales instead of skin. Fish use fins and a tail to swim around. Baby fish hatch from eggs. A person who studies fish is called an ichthyologist
