DESCRIBING ANIMALS.
Here you have some useful words to describe the bodies of animals:
 According to the place they live they can be land animals or aquatic animals. There
are also parasitic animals.
 Regarding the size of the animal we can use these adjectives: large, small, medium
sized...
 Shape. Animals can be round like an urchin, long like a worm, flat like a fish...
 A mammal’s body can be divided into a head, a trunk and limbs while an insect’s body
includes a head, a thorax and an abdomen.
 We can distinguish different kinds of limbs: legs for walking, wings for flying and fins
for swimming.. Human beings have fingernails but cats have claws which are sharper
and longer. Horses have hooves.

Many mammals have a tail, the octopus has tentacles and many arthropods have
antennae.
 Our skin is covered in hair but fishes and reptiles have scales. Birds are covered in
feathers and can also be recognised by their beaks.
Inside our bodies there are bones. Other animals haven’t got bones; their bodies are soft or
are protected by a shell; a very hard shell like those of molluscs or not so hard like the shells of
insects or prawns. The vertebrates have got backbone and the invertebrate haven’t got it.

Unit 5 y 6. Animals Science 1º ESO
There are several respiratory systems by which animals feed themselves. Aquatic animals use
gills to breathe but land animals have lungs. Land arthropods have a net of tiny pipes called
tracheae.
Fertilization, that is the union of sexual cells, can take place in the environment (external
fertilization) or inside the female’s body (internal fertilization). The internal one is more
common for land animals. The embryo develops inside an egg, either outside the mother’s
body (oviparous animals) or inside the mother’s body (viviparous animals).
1. In complete sentences, describe a grasshopper using the correct words from this list. (20
words) long, small, pink, jump, wings, fins, green, invertebrate, short, vertebrate, big, swim,
aquatic, land, red, mollusc, insect, fly
Example: A grasshopper is green.

Unit 5 y 6. Animals Science 1º ESO
It has got four legs, fur, a tail,
whiskers and a nose
It can be many different colours
but mainly white, black, orange and brown.
It is not very big. It is usually
smaller than a dog.
Food.
It eats lots of meat like mice,
insects and birds.
Enemies
Its enemies include dogs, wolves
and foxes.
Habitat and location (country, continent).
It is located all over the world.
Population. Is it endangered?
It is not endangered.
Abilities (jump, climb, run, hunt, fly…).
It is very good at running and
jumping.
VERTEBRATES AND INVERTEBRATES
Depending on their backbone or spinal column we can distinguish two groups:
 Vertebrates. Animals that have got a backbone. It is a part of an internal skeleton.
 Invertebrates. Animals that have not got an internal skeleton with a backbone. Some of
them have not got a skeleton (like worms and jelly-fish) and others have got an external
skeleton (like insects, spiders, and crabs).
Which group is the largest?

VIDEO.THE EXOSKELETON. From Anaya Digital. Fill in the gaps.
This takes different forms, for example in many beetles, the first pair of wings forms a concave
shield which is hard and even. This makes capturing a beetle difficult, but in any case it is better
for it to hide. In other beetles, such as this male flying deer beetle, which is almost 6cm long,
the armour of the jaws forms huge defences which look 1)________. Predators do not know that
they are not really dangerous. Another form of defense is 2)_________. This happens with this
harmless cerambycidae whose black and yellow exoskeleton make him look like a dangerous
wasp. Indeed, it moves the same way that wasps do. Other insects have exoskeletons with bright
colours to indicate a real danger, for example this monarch 3)_______ warns that it is poisonous
through its colours, a striking combination of orange and 4)_______.

Unit 5 y 6. Animals Science 1º ESO
Some questions:
1) Give three examples of how insects are protected in the environment.
2) Is the cerambycidae a dangerous insect?
3) What is the advantage for a beetle to have smooth and even wings?
Activity 6. How many groups of arthropods are there? Explain the differences between
insects and arachnids.
Activity 7. Try to classify all the invertebrates in activity 3 in its group.

VERTEBRATES
Mammals and birds are warm-blooded, which means that they can make their own
body heat even when it is cold outside.
Cold-blooded animals, like reptiles, amphibians, and fish, become hotter and colder,
depending on the temperature outside

VIDEO. The Metamorphosis of Frogs Fill in the script.
The typical formula of amphibians´ growth is very interesting and it is similar to that of insects.
These animals also undergo some type of metamorphosis. Most of them lay huge quantities of
1)________ which when they hatch produce animals in their lavae phase. The larvae of frogs and
toads are called tadpoles. At first, they do not have legs and they are just a head and a 2)_______.
During this stage, their life is totally aquatic and they breathe through gills, the same as fish do.
They feed mainly on vegetation, although they also eat carrion and if there are few sources
available, they even become 3)_________. The key is to grow fast and to become a real amphibian
as soon as possible. Their legs develop wrapped up by the epidermis (outer layer of skin). The hind
legs show first and this helps them to develop their cabability of 4)_________, then the forelegs
show. When a limb is completely developed, a small hole opens in the skin and making a
movement, they pull that limb out, as we would pull out our arm through a shirt sleeve. As all this is
happening, the 5)________ and the rest of the organs are preparing for a future when everything
will be different: their diet, their breathing and the way they move. Their external experience is also
changing and little by little the tail is reabsorbed. The head and the rest of the body now have the
appearance of a new animal, an animal which will live by 6)_________ between Earth and water.
Bonus question! What is the name of a baby frog or toad?

MAMMALS. DISCOVERY CHANEL VIDEO. Fill in the script with these words
Tools/ claw/ reptiles/ climates/ apes/ sea/ whales/ Limbs/ glands/ hair/ eight/ oceans/ mammals
Mammals from giant______ to small mice, to great apes much like ourselves, are among the most
advanced of Earth's creatures. All __________share two traits: we feed our young with mothers
milk, and we have_____ (more or less). Mammals nursing other young produce fewer offspring
than other animals but the youngsters have a much higher rate of survival than newly hatched birds,
______ and insect. This young orangutan will stay with its mother for _______ years.

Hair, like the coats worn by these high alpine guanacos offer mammals another advantage: hair and
the sweat ________that come with it helps mammal stay warm in cold_________. Overtime
mammals have moved into nearly all earth’s habitats polar______ have adapted to life in the Arctic
where the inhospitable cold makes fur coats essential. Marine mammals like porpoises and
humpback whales thrive in cold_________. They still have a few hairs around their mouths but a
more efficient underwater_________ is a thick layer of fat keeping heat in and cold out. Elephants
battle heat their skin covered in fine hairs is wrinkled making it easy to trap cooling mud in the
creases. Pots on the coats of leopards and cheetahs help them hide.

Their fur works to camouflage the big cats stalking prey in tall grasses. There are seventy five
hundred species of reptiles and amphibians and some 8600 species of birds only forty one hundred
species of mammals exist but they dominate the land and_____. The mammals have evolved with
greater speed and agility than most other animals. ______that are lined up to support weight and
drive mammals forward help browsing mammals run from mammalian predators armed with tooth
and______. And when natural advantages fail some mammals fashion ________to help them out.
3:03
this orangutan is working on a spoon to help him scoop ants out of a tree. Toolmaking was once
thought to be a skilled exclusive to the human mammal but all great______ and some other animals
make tools. So what separates us from the rest of the mammals? Our ability to communicate, to
parent, to show emotion. Perhaps a better question is to ask what makes us all so alike.
