Animals belong to five big groups. The groups are fish, amphibians, reptiles, birds, and mammals. Each group has its own special features.
Leo sees a goldfish. It has gills and swims in water. It is a fish.
Look for clues. Feathers mean bird. Fur means mammal. Gills mean fish.
Every animal fits one group, and each group has its own clue.

15.6 Vertebrates
Some animals have a backbone inside their body. We can sort these animals into five big groups.
Fish live in water. They breathe with gills. A goldfish is a fish.
Amphibians can live in water and on land. A frog is an amphibian.
Reptiles have dry, scaly skin. Snakes and lizards are reptiles.
Birds have feathers and wings. A robin is a bird.
Mammals have fur or hair. Mother mammals feed their babies milk. Dogs, cats, and whales are mammals. You are a mammal too!
29.4 Reptiles
Reptiles are animals with dry, scaly skin. Snakes, lizards, turtles, and crocodiles are all reptiles.
Most reptiles lay eggs on land. The eggs have a tough shell that keeps the baby safe.
Reptiles love the sun. They warm their bodies in the sunshine. Then they have energy to move and hunt.
Look at a picture of a snake. See its shiny scales? Those scales tell you it is a reptile.
29.6 Mammals
Mammals are animals with fur or hair. Dogs, cats, bats, and whales are all mammals.
Mother mammals make milk for their babies. Baby cats and baby dogs drink milk from their mothers.
Some mammals are very big, like the whale. Some are very small, like a mouse. But they all have fur or hair, and they all feed their babies milk.
Guess what? You are a mammal too.
20 Fascinating Animals Which Start with X
Can you think of an animal that starts with the letter X? Here is one.
The X-ray tetra is a fish. It lives in rivers in South America.
This little fish is very special. You can see right through its skin. Its see-through body helps it hide from hungry animals.
The X-ray tetra swims and breathes with gills, just like other fish. So it belongs to the fish group.
