Vertebrates are animals that have backbones. They are classified into five main groups: fish, amphibians, reptiles, birds, and mammals. Fish lay eggs and breathe through gills. Amphibians live both on land and in water, laying eggs in water. Reptiles include lizards, snakes, and turtles. Birds lay eggs, are warm-blooded, and have feathers. Mammals are warm-blooded, give live birth, and have hair or fur.
