Animals Information

ANIMALS ARE LIVING THINGS


Animals are born, grow, reproduce and die. 

Animals need food, water and oxygen to stay alive.

We can classify animals into two big groups:

  -Vertebrate animals: they have a skeleton or backbone inside.

 -Invertebrate animals: they don't have a skeleton or backbone inside. 

 


VERTEBRATE ANIMALS

        They have a skeleton inside.  
        They are divided into 5 groups: mammals, birds, reptiles, amphibians and fish.

 

1. Mammals

* Mammals are viviparous. 
* They give birth and they have live babies.
* Mammals drink their mother ́s milk.
* Mammals have hair or fur.
* Most mammals have four legs.
* Mammals breathe with their lungs.


 

 

   2. Birds 

*Birds are oviparous. They lay eggs. 
*Birds have two legs, two wings and a beak. 
*Birds have feathers. Most birds can fly.
*Birds breath with lungs. 

 



3. Reptiles 

*Reptiles are oviparous. They lay eggs.
*Some reptiles have legs and some have no legs.
*Reptiles have scales or a shell. 
*Reptiles are cold-blooded. 
*Reptiles breathe their lungs.


 

4. Amphibians 

*Amphibians are oviparous and lay eggs in the water! 
*Amphibians have wet or moist skin.
*Baby amphibians live in the water. Adults live on land.




          5. Fish

         *Fish are oviparous. 

         *They lay eggs. 

         *Fish live in the water.

         *Fish have scales and fins.

         *Fish breathe with their gills.

         



INVERTEBRATE ANIMALS

 

        They don't have a skeleton inside.

        Some of them have soft bodies; others have a shell or exoskeleton to protect their bodies.




        All invertebrates are oviparous: they lay eggs.

        We can classify invertebrates into: arthropods and molluscs.


Arthropods

*Most live on land.

*They have many legs. 

*They have a hard body or exoskeleton.

 





Molluscs 

*Most live in water

*They have soft bodies, but some have shells or tentacles.
