ANIMALS THROUGHOUT THE WORLDSanta Gema Galgani becomes a zoo!

ANIMALS ARE AMAZING LIVING THINGS…

IN GROUPS:• You are going to choose an animal. • Any animal will do it. Just think the

animal that you would like to choose and choose it.

• It has to be a REAL animal. A dinosaur does not count; we are talking about animals that live nowadays.

• Once you have chosen your animal, you are going to complete the chart given about the features this animal presents.

• Think if the animal:• Is vertebrate or invertebrate• Is a herbivore, carnivore or

omnivore animal.• Is a viviparous or an oviparous

animal.• Has special features: where does

it live, etcétera.

ANIMAL FEATURES

VERTEBRATES AND INVERTEBRATES

VERTEBRATE ANIMALS• Vertebrate animals are those

animals that have a backbone and a bony or cartilaginous skeleton. Mammals, birds, reptiles, amphibians and fish are vertebrate animals.

INVERTEBRATE ANIMALS• Invertebrate animals are those

animals that don’t have a backbone or spinal chord. Most of the animals in the world are invertebrates.. Sponges, cnidarians, molluscs, arthropods, worms and echinoderms are invertebrate animals.

NUTRITIONHERBIVORES

• Herbivore animals are those animals that only feed on plants. Cows are herbivore animals.

CARNIVORES• Carnivore

animals are those animals that only feed on other animals and only eat meat. Lions are carnivore animals.

OMNIVORES• Omnivore

animals are those animals that can both feed on animals or plants. Humans or bears are omnivore animals.

REPRODUCTION

VIVIPAROUS ANIMALS• Viviparous animals develop

their babies inside the mother’s belly. Mammals are viviparous animals.

OVIPAROUS ANIMALS• Oviparous animals develop their

babies outside the mother’s belly. They develop inside eggs. Birds, fish or amphibians are oviparous animals.

YOUR ANIMAL’S DESCRIPTION

Now, we are going to describe our own animal, the one that we have chosen. We will follow the next path: features (nutrition, reproduction…) and then, using the information that you found, complete the description.

VERTEBRATE ANIMALS

MAMMALS• Mammals are viviparous animals, with their skin covered with hair or fur,

and breathe the air through the lungs. There are four different groups:• Carnivore mamals.• Mammals with hooves: instead of toes, these mammals have hooves.

Most of them are herbivore, and some are omnivores.• Primates: they have five fingers in each hand and five toes in each feet.

Human beings belong to this group.• Cetaceans: they are aquatic mammals. Unlike fish, they have lungs, so

they have to take air through their blowhole once in a while to survive. Dolphins or whales are cetaceans.

MAMMALS: viviparous,

vertebrates, hair or fur, lungs.

BIRDS Birds are oviparous animals with the body covered with feathers. Most of them use their wings to fly, and they have a beak to eat instead of a mouth. They breather through their lungs. There are four different types of birds:• Flightless birds: they cannot fly. Ostriches are flightless birds.

• Waterfowl: their feet are prepared to swim. Swans and ducks are waterfowl.

• Birds of prey: they are carnivores. They have strong claws and beaks. Eagles are birds of prey.

• Songbirds: they are the largest group.

BIRDS: oviparous, feathers, wings,

lungs.

REPTILES• Reptiles are vertebrate, oviparous animals. Most of them are terrestrial. They have their body covered in scales, and breather air through their lungs. There are four different groups:

• Lizards: terrestrial, carnivorous animals. They have short legs and a tail. Some can remove the tail to confuse predators.

• Snakes: they have no legs, and slither on the ground. • Crocodiles: they have their bodies covered with hard

scales. They are carnivore, and crocodiles and alligators belong to this group.

• Tortoises and turtles: they have a hard Shell. Tortoises are terrestrial, and turtles are aquatic.

REPTILES: oviparous,

vertebrates, scales, lungs.

AMPHIBIANS• Amphibians are both aquatic and terrestrial, and oviparous animals. They have four legs, and their skin is bare. They breathe through their lungs and skin. • They Suffer metamorphosis. Metamorphosis

is the process of changing from a tadpole to an adult amphibian.

AMPHIBIANS: terrestrial and

aquatic, vertebrates, bare skin, lungs and

FISH•Fish are aquatic, oviparous vertebrates. They breathe through their gills, and their bodies are covered with scales.

INVERTEBRATE ANIMALS

INVERTERBRATE ANIMALS•There are lots of animals that are

invertebrates. They don’t have a backbone (also called spinal chord)

•There are six groups: sponges, cnidarians, worms, molluscs, echinoderms and arthropods.

SPONGES• They are very simple. They cannot move by themselves. • Their sac-like bodies are covered of pores. • They filter the nutritive substances in seawater for food.

CNIDARIANS• They are aquatic invertebrates.• They have got jelly-like bodies that look like UMBRELLAS.• They have poisonous tentacles.

WORMS• They have long, soft bodies.• They haven’t got legs.• Some live in the soil (like the earthworms) and other live in water

(fireworms)

MOLLUSCS• They have soft bodies, and protect themselves with one or two shells.• They are oviparous.• There are different groups:

• Bivalves• Snails and slugs.• Squids and cuttlefish.• Octopuses:

MOLLUSCS: Soft bodies, shells,

oviparous.

ECHINODERMS• They have a “skeleton” made of hard plates, often with spines.• They are marine animals.• There are two groups:

• Starfish

• Sea urchins

ARTHROPODS• They are the largest group of animals.• They have exoskeletons (like an armour)• They have got legs and a segmented body.• There are four groups:

• Insects• Arachnids• Crustaceans• Myriapods

ARTHROPODS: EXOSKELETON,

SEGMENTED BODY, LEGS

Insects

Crustaceans

Arachnids

Myriapods

INSECTS• They all have SIX LEGS and most of them TWO ANTENNAE.• They can have either TWO or FOUR wings.• The body is divided in three parts:

• The head: with the mouth, eyes and the antennae.• The thorax: has got six legs and the wings.• The abdomen.

They are oviparous and Suffer from Metamorphosis too.

OTHER ARTHROPODS

ArachnidsThey have eight legs. They haven’t got antennae.They produce silk to create their webs.

CrustaceansThey have a hard exoskeleton.They have got antennae and ten legs.

MyriapodsThey have long bodies.They have many identical segments.They have got a pair of antennae.
