A western toad is an amphibian. It has moist skin and begins its life in water.
Toads do not have teeth! They swallow their food whole.
A whale shark is a fish. It lives underwater. It has fins, not limbs.
Whale sharks are the largest fish in the world! Adult whale sharks can weigh over 21 tons—as much as seven elephants!
A spotted dolphin is a mammal. It has hair and feeds its young milk.
Dolphins may look like sharks or other fish, but they are mammals! When a baby dolphin is born, it has hair around its jaw. This hair falls out as the dolphin grows.
A Hermann's tortoise is a reptile. It has scaly, waterproof skin.
A tortoise's shell protects it from predators. When a tortoise feels threatened, it can pull its head and legs inside its shell.
