VERTEBRATES

Vertebrates are the group of animals that have a spinal column and skeleton.

Vertebrates is divided in 5 groups: fish,birds,reptiles,amphibians and mammals.

Fish are the largest group of  vertebrates.They live in water.Fish live in salt water, rivers, lakes or oceans.Most fish lay eggs.Fish take oxigen of  water through their gills.Fish have fins and a tail,with them swim..Their body is covered with scales,with protect them.

 Birds live on land and have 2 wings., bird´s body is covered with feathers.Birds do not have teeth: they have a beak. Some birds can swim; their feet are specially.Birds are oviparus.

Reptiles breathe through their lungs.All reptiles have thick, hard scales covering their body.Some reptiles have 4 short legs.they move to one place to another by crawling.Other reptilesdo not have any legs.They move by slithering.

Amphibians live part of their life in water, and part of the land.When they are young live in water and breath through their skin and gills.When they become adults they live on land and breathe through their lungs. An amphibian`s skin is moist.They have 4 legs.Amphibians are oviparus.When their are babies look different from their parents.As they grow,their body changes, these changes are cold metamorphosis.

invertebrates

Invertebrates is the group of animals that not have spinal column, and skeleton.
Invertebrates is divided in 6 groups: arthropods, molluscs, worms, echinoderms,sponges
and cnidarians.
Arthopods are divided in: insects, arachnids, crustaceans and myriapods.
Their body is divided in three main parts:  head, thorax and abdomen.
Molluscs are divided into gastropods bivales and cephalopods.
Molluscs do not have y legs.To move to one place to another,they use  a muscular foot.
Wormsdo not have legs, their bodies are long and soft.they are not protected by exoskeletons or shells.Their body divided into rings.

THE HEART

        
     
The heart is the most important organ of the circulatory sistem.The heart is like a big pump that  ejects the blood through everywhere into the body , everytime that it  beats .  
This is the way how the organs get nutrients and oxigen. The heart has arteries to get its own nutrients and oxigen too.
