Unit 3: Animals
1. Classify these animals into these two groups:
hen – octopus – ant – toad – shark – parrot – snail - ladybird
VERTEBRATES INVERTEBRATES
1. VERTEBRATES AND INVERTEBRATES
Animals are living creatures. They are born, grow,
reproduce and die.
We classify animals into 2 big groups:
o Vertebrate animals:
Vertebrates have a skeleton inside them.
An important part of this skeleton is the
backbone.
Most vertebrates have a head, a trunk, limbs and
a tail.
o Invertebrate animals have not got bones.

2. Read and complete these sentences:
________animals have got bones. The following are vertebrate
animals:______________________________________.
___________animals ________got bones. The following are
invertebrate animals _____________________________.
3. Draw a vertebrate and an invertebrate animal and write
their names into the boxes.
4. Write HAVE or DON´T HAVE to make true sentences:
Dogs _____________________ a tail
Birds _____________________ a backbone
Rabbits _____________________ a tail
Bears _____________________ limbs
Snakes _____________________ limbs
Fish _____________________ backbone
Frogs _____________________ a tail

5. Classify these animals according where they are born from.
Duck-tiger-snake-elephant-whale -bear-leopard-lizard-seagull-
dolphin
OVIPAROUS VIVIPAROUS
6. Write the word that doesn’t belong.
a) turtle, toad, fish, goat _____________________________
b) shark, dolphin, chicken, salmon ________________________
c) seagull, eagle, bat, frog ______________________________
2.-OVIPAROUS AND VIVIPAROUS ANIMALS
According to where animals are born from we can classify
them in:
Oviparous: They are born from an egg. Examples: fish,
frogs and chickens.
Viviparous: They are born from their mother’s womb.
Examples: zebras, whales, bats and “humans”.

3. VERTEBRATES
We can classify vertebrates into 5 groups: mammals, fish,
birds, amphibians and reptiles.
Mammals
Mammals are viviparous.
Most have hair or fur.
Some live in the water, but most live on land.
Some can fly.
Fish
Fish are oviparous. They are born from eggs.
They have scales.
They live in water.
Birds
Birds are oviparous.
They have feathers.
Most birds can fly.
Amphibians
Amphibians are oviparous.
They don’t have scales or hair. They just have skin.
They live in water and on land.
Reptiles
Reptiles are oviparous.
They have scales. Some have a shell.
Some live in water, but most live on land.
Some have four legs and walk like crocodiles and
chameleons. Others slither along the ground, like the
snake.

7. Write IS or ISN´T:
It ________viviparous. It ________ viviparous.
It ________oviparous. It ________oviparous.
It ________a water animal. It ________a water animal.
It ________ a water animal. It ________ a water animal.
It ________ a fish. It ________ a fish.
It ______ a reptile It ______ a reptile
It __________a turtle. It __________a turtle.
It _________ a goat. It _________ a goat.
8. Read and circle the correct words. Then colour the picture.
“My name is Max. I am a fox / pig / chick . I am a bird
/mammal / reptile , because I drank / ate my mother’s milk
when I was a child / baby . I am a vertebrate / invertebrate
animal. This means that I have / haven’t a skeleton made of
many muscles / bones / joints . I live on land / in water. I am
a wild / domestic animal”.

9. Read, draw and colour.
Spiky is a parrot, so he is a bird.
He lives in the jungle, in a very tall and green tree.
He has got five white eggs in his nest.
He has got a big, red beak and two orange legs.
His body is covered with feathers. His body is green and
his wings are colourful.
Today is sunny and Spiky is flying in the sky.

10. Label this picture. You can use the words in the box.

11. Write TRUE or FALSE.
Fish have hair.
Fish are oviparous
Fish are vertebrate animals.
Fish have wings.
They have fins.
They live in water and on land.
They have scales.
Tuna, whale, shark and salmon are fish.
12. Draw these animals in the correct box: snake- turtle- lizard-
crocodile.

4.- INVERTEBRATES
Those animals that haven’t got a skeleton inside them are
invertebrates.
They are usually smaller than vertebrates.
All invertebrates are oviparous.
Most animals on the Earth are invertebrates.
Some are land animals and some are water animals.
5.- CLASSIFIYING INVERTEBRATES
It is more difficult to classify invertebrates because
there are so many groups!
The most important groups are:
Molluscs
Have a soft, muscular body.
Some, like snails, have a shell.
Mussels, oysters and octopuses are all molluscs.
Arthropods
Is the biggest group of invertebrate.
Their bodies are divided into 3 parts.
Insects and arachnids are arthropods.
Insects have six legs and two antennae.
Worms
Have a long soft body.
They don’t have shells.
Jellyfish Sponges Starfish

17. Classify these animals:
mosquito – snake – toad – fly – horse – ant – lizard – bat

19. Match.

only other animals.
only plants.
plants and other animals
6.-WHAT DO ANIMALS EAT?
According to what they eat we can classify animals in:
Herbivores: Are those who only eat plants, like rabbits
Carnivores: Are those who only eat meat, like lions.
Omnivores: Are those who eat plants and meat, like bears
I eat insects.
I eat fruits and seeds.
I eat roots, fruits and fish.

20. Guess the animal.
It is an animal that is vertebrate, carnivore, oviparous, whose body is covered
in scales and live in the water._____________________________________
It is an animal that is vertebrate, herbivore, viviparous, whose body is covered
in fur and lives in land __________________________________________
It is an animal that is vertebrate, carnivore, oviparous, whose body is covered
in feather and lives in water and on land _____________________________
21. Think and answer:
Octopuses are in this group. ______________________________________
Snails are in this group. _________________________________________
Spiders are in this group. ________________________________________
Insects are in this group. ________________________________________
Sponges are in this group. _______________________________________
They only live in the sea. ________________________________________
This is the biggest group of invertebrates. ___________________________
22. Match.

7.-WHERE DO ANIMALS LIVE?
Domestic animals live near people, and some of them give us food.
Example, hens give us eggs.
Pets are domestic animals that live in our houses. Example:
canaries, dogs, hamsters, ...
Wild animals live in the wild. They can live on land (forests,
deserts, jungle, ...), in water (seas, rivers or lakes) or in the air.
They do not need people to get food.
23. Write all the animals you can remember. Then circle:
DOSMESTIC ANIMALS WILD ANIMALS
Circle with a green pencil, the animals that live on land.
Circle with a blue pencil, the animals that live in water.
Circle with a yellow pencil, the animals that live in the air.
