Unit 5 Animals

1.    Classification

We can classify animals in differente ways, depending on the way they are born, how they reproduce and what they eat. We classify them according to their skeleton.

A)   SKELETON:

·      Animals with bones are called VERTEBRATES. Vertebrates have an internal skeleton. All vertebrates have a spine.  Vertebrates are: Mammals, birds, fish, reptiles and amphibians

·      Animals without bones are called INVERTEBRATES.

Invertebrates are: arthropods, molluscs and worms

B)   WAY THEY REPRODUCE

·      VIVIPAROUS: Animals that are born from their mothers´wombs.

·      OVIPAROUS: Animals that are born from eggs.

C)   WAY THEY EAT

·      CARNIVORES: They eat meat and other animals

·      HEBIVORES: They eat grass and plants.

·      OMNIVORES: They eat both meat and plants.

_______________________________

They usually live on land, they breathe with lungs, they have hair on their bodies, they are viviparous and they can be carnivores, hebivores or omnivores. ______________________________

They are invertebrates, they have six legs, their bodies are divided into three parts, head, thorax and abdomen, many of them have wings and can fly.

______________________________

They are born from eggs, so they are oviparous. They also lay eggs, the have wet skin and they live both in water and on land. __________________________
