Vertebrates
As you know, we can
classify animals in various ways, depending on the characteristics we look at.
Today, we’re going to some animals by the internal structure of their bodies. According to this feature, we can classify them into... Vertebrate Animals, which have an internal skeleton, that means bones.... And Invertebrate Animals... like this worm, which has no backbone... in fact, no bones at all.
All vertebrate animals
have an internal skeleton made up of... bones.
Bones are very strong,
and give bodies their shape, they hold it up, nice and straight.
The spine – the backbone – is made of a series of articulated pieces of bone, called the vertebrae, which allow the body to move in a certain way, and flexible.

Vertebrate animals’
bodies are divided into the head... the torso... and the limbs ... Yes ......
the head ... the body... and the arms and legs.
Some vertebrates are
aquatic... like these fish ... Others are terrestrial... like this bear. And
other fly... like this eagle.
Vertebrates can move in many different ways... walking... jumping... crawling... climbing... and when they have running ... but sometimes it’s not enough.
There are also many vertebrate animals that move by flying, like birds and bats. For example, these eagles... which unfortunately for the fox, are much faster than him.
Vertebrates
are classified into five groups: Fish... Reptiles... Amphibians ... Birds...
and Mammals... like this big howler monkey.
Now let's remember the most important things we’ve learnt about vertebrate animals.
Vertebrate animals can be classified into 5 groups: Fish... reptiles... amphibians, birds... and mammals.
