’ VERTEBRATES are animals that have a skeleton inside their bodies. An internal skeleton includes a backbone which is made up of bones called vertebrae.

The main
characteristics of vertebrates are:
they have
t
their
bones
body
is divided into
and
backbone .
head, trunk and
limbs.
they have
bilateral symmetry.
Vertebrates
can be classified into five groups, based on their skin
covering, how they reproduce, how they maintain body temperature, and characteristics of their limbs (arms and legs, or their equivalent such as wings or fins). There are five groups:
birds
mammals
amphibians
fish
reptiles

HOW DO YOU KNOW IT IS A FISH? It is a fish because...
It is cold-blooded.
Their skin is covered with scales.
They breathe with gills (
They are aquatic vertebrates.
Their limbs are modified into fins (
).
) for swimming.
They are oviparous, lay eggs in water
THERE ARE TWO KINDS OF FISHES - bony fishes have a swim bladder. About 95% of fishes have skeletons made of bone.
- Fishes with a cartilage skeleton tend to be heavier than water and sink. They must swim to keep afloat. Cartilaginous fish include the ray and the shark.

HOW DO YOU KNOW IT IS AN AMPHIBIAN? It is an amphibian because... It is cold-blooded. They have no scales, hair, or feathers, their skin is humid . They are oviparous, lay eggs in water.
METAMORPHOSIS their life cycle has two stages: pollywog , larval stage, lives in water breath with gills
adult stage live in land and breath with lungs and through their skin.
THERE ARE TWO KINDS OF AMPHIBIANS: Anurans : without tail
Urodela : with tail

HOW DO YOU KNOW IT IS A REPTILE ? It is a reptile because...
It is cold-blooded. They have scales They have short legs or without legs
They have dry scaly skin.
They have lungs for breathing. They are land animals. They are oviparous, they lay eggs with hard shell on land. They are carnivors. They crawl or slither ( skate)
THERE ARE FOUR KINDS OF REPTILES:
Snakes
Lizards
Turtles
Cocodrilians

HOW DO YOU KNOW IT IS A BIRD ? It is a bird because...
It is warm-blooded.
They have feathers, beak, claws and wings.
They lay eggs with hard, waterproof shells
They breathe through lungs with air sacs.
Air sacs
The most can fly.
Their bones are lightweight and usually hollow.
They have different beaks in shape and size depend on their way of feeding: predators, fish-eating, catch insects, feed off larvae and worms.

HOW DO YOU KNOW IT IS A MAMMAL ? It is a mammal because...
It is warm-blooded.
They have four limbs in the form of pota, wings or fins.
They have hair or fur on their bodies.
They are viviparous.
They breathe with lungs.
They have mammary glands (milk-secreting).
They live on land and in the sea, mammals are everywhere. They can be carnivore, herbivore or omnivore. The largest mammal is the blue whale which often exceeds 30m in length
Human beings are mammals. Material creat per Marian Ruiz Simón- Projecte AICLE- Escola Túrbula 2014
There are three different groups based on reproduction methods:
Monotremes -egg laying mammals
Duck billed platypus
Marsupials -give birth to very undeveloped young that develop inside the pouch
kangaroo
Placentals -young develop inside mothers body, nourished by an organ called the placenta.
Giraffe
