1. Vertebrate and invertebrate animals

Lesson 1. Vertebrate and invertebrate animals


Here you have this video in which you will find information about vertebrate and invertebrate animals. 

Under the video you have got the text transcription just in case you do not understand something. Clicking on the unknown word you will be redirected to a dictionary.

The terms vertebrate and invertebrate are used often in classrooms and the media so they're worth learning.

First of all, only about 1-3% of the animal species are vertebrates. The main groups are fish, amphibians, reptiles, birds (which are considered a group of reptiles) and mammals. They all have a chain of bones called vertebrae that you can feel in middle of your own back.

Vertebrates are a subgroup of the chordate phylum. All chordates have a nerve chord along their backs but some little-known species, such as sea squirts, don't actually have vertebrae surrounding that chord. So not even all chordates are vertebrates!

Invertebrates is a name thrown at everything else: arthropods (insects, arachnids, crustaceans and others), mollusks (snails, clams, octopus and many more), anthozoa (corals, jellies, anemones to name a few), echinoderms (sea stars and urchins) sponges, all the various worms, and a bunch of other stuff you've probably never heard of and, unless you go deep into biology, will probably live your life in blissful ignorance of (bryozoans, anyone?). 

In the following video you can look into vertebrate animals.

Today we’re going to look at vertebrate animals.
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.
Vertebrates have internal skeleton made of bones...
The body of this kind of animal is divided into head, torso and limbs...
They move in many ways: walking, jumping, crawling, flying, climbing and when they need to, running....
