account 
Different animals have different kinds of features and characteristics. Some animals have hair or fur, while others have scales. Some animals give birth to babies, while others lay eggs that hatch. Just like certain animals are mammals or reptiles or amphibians (and so on) because of their special features, some creatures fall into the category of fish!
Fish are animals that are vertebrates (they have a backbone), cold-blooded, and live in the water. Fish lay eggs, and generally, fish also usually have scales and fins, tails, and gills instead of lungs.
There have been fish living on Earth for over 450 million years. They live in bodies of water all over the world, from freshwater lakes to big salty oceans!
