This document discusses the five main groups of vertebrate animals: mammals, reptiles, birds, amphibians, and fish. It provides characteristics for each group and examples. Mammals are defined as animals that are warm-blooded, feed their young milk, have hair or fur, and are viviparous. Reptiles have scales and lay eggs. Birds have feathers and a beak, most can fly but some cannot, and they lay eggs. Amphibians live both on land and in water, have moist skin, lay eggs in water, and breathe through gills as larvae and lungs as adults. Fish breathe through gills, live in water, have fins and scales, and lay eggs

2. There are five different groups:
·Mammals
·Reptiles
·Birds
·Amphibians
·Fish

3. Mammals
Characteristics
• Mammals are vertebrates because they have bones inside their
bodies.
• Baby mammals feed on their mother's milk.
• Most mammals bodies are covered with hair or fur, but sometimes
we cannot see it.
• They are viviparous animals because they are born from their
mother’s womb.
• They breathe through their lungs.

4. Marine Mammals
·Not all mammals live on land. Some mammals live in the sea like the
dolphin, the whale ....
·They also breathe through lungs so they need to go to the surface from
time to time to breathe.

5. Flying mammals
·Bats can fly but they are also mammals.
·Bats are blind, they cannot see but they know
where to go thanks to their big ears. They use
their sense of hearing to move around.

6. Mammals can be:
· Carnivores: they eat meat, like the lion, the tiger….
· Herbivores: they eat plants like the cow, the rabbit, the
squirrel…
· Omnivores: they eat meat and plants like the bear, the pig …

· The giraffe is a ___________________ animal because it eats plants.
· The cow is a ______________ because it has bones inside its body.
· The pig is an ______________ animal because it eats meat and plants.
· Mammals breathe with their ______________________
· The whale is a ______________ because it lives in the sea.
· Cats are ________________ because they come from their mothers womb.

8. Reptiles
·Reptiles have dry skin and their body is covered in scales.
·Reptiles are cold-blooded.
·Reptiles breathe air through lungs.
·Reptiles lay eggs, they are oviparous.
·Reptiles have short legs or not legs at all (like snakes)
·Most reptiles don't incubate their eggs, take care or feed their babies.

9. Birds
·All birds have feathers, but not all birds can fly.
·All birds have a beak and two wings.
·They have two legs covered in scales.
·Birds are warm-blooded.
·All birds hatch from eggs, they are oviparous.
·All birds breathe with lungs.

10. Aquatic birds
·Penguins are aquatic birds
·They only live in the southern hemisphere
·They cannot fly
·They breath air through their lungs
·They are born from eggs, they are oviparous
·They eat eat fish, squids ...

11. Amphibians
·Amphibians are animals that are born in water and grow to live on land.
·They have smooth, wet skin.
·Amphibians are cold-blooded.
·Amphibians lay eggs in water, they are oviparous.
·Amphibians breathe with gills when they are small, and then with lungs
when they are adults.
·Frogs, toads, and salamanders are all examples of amphibians.

13. Fish
·All fish breathe with gills.
·The live in water. They can live in fresh or salt water.
·They can swim usin their fins.
·Their bodies is covered in scales.
·The are oviparous.
·Fish are cold-blooded animals.
