ANIMAL KINGDOM
3
The animal kingdom is made up of two main groups

• ANIMALS WITHOUT BACKBONES
• These animals without backbones are called
• INVERTEBRATES
• Molluscs
• Worms
• Arthropods
• Echinoderms
• Coelenterates

• ANIMALS WITH BACKBONES
• These animals with backbones are called
• VERTEBRATES
• Mammals
• Birds
• Reptiles
• Amphibians
• Fish

We are vertebrates and have a skeleton to keep us
upright and to help us to move

MAMMALS

• They are warm blooded animals or
• they can regulate their own
• temperature.
• Mammals retain the young in their
• bodies until they are ready to be
• born. When the young are born
• they are fed by the mother on milk.
• Most mammals have hair, four legs
• and tail. However aquatic mammals
• have fins and a smooth, hairless
• skin.

MAMMALS
the blue whale

• Mammals have a highly
• developed nervous system.
• They live on land and in the
• sea.
• The largest mammal is the
• blue whale which often
• exceeds 30m in length.
• Shrews and mice are the
• smallest. They are often less
• than 5cm, excluding their tail.

BIRDS

• They are warm blooded
• vertebrate animals with wings and
• bodies covered with feathers for
• warmth and to help them to fly.
• Birds have lungs for breathing and
• a heart with four chambers.
• All adult birds are covered in
• feathers even though some are
• born naked.

BIRDS

• The female lays her eggs in nests
• and the young are cared for by the
• adult birds until they grow and are
• able to leave the nest.
• Many people believe that birds can
• be identified by their ability to fly,
• but that's not true. Although all
• birds have wings, not all birds can
• fly!.....and not all animals that can
• fly are birds.
• All birds have feathers .. and they
• are the only animals that have
• feathers!

REPTILES

• Reptiles are cold blooded
• vertebrates. This means they
• cannot maintain a body
• temperature much different than
• their environment.
• A reptile's skin is usually covered
• with dry scales.
• All reptiles are carnivorous. They
• eat insects or the flesh of other
• animals.
• They breathe through lungs

REPTILES

• Most reptiles lay eggs with hard
• shells and they hatch as small
• versions of the adult.
• The young hatch fully formed,
• without a larval stage, ready to
• seek their own food and care for
• themselves.
• Reptiles have been on earth for
• over 300 million years .. that is
• a very long time!

AMPHIBIANS

• They are cold blooded vertebrate
• animals that generally spend their
• larval or tadpole stage in fresh
• water.
• They live on water and land, but
• breed in water
• Amphibians were the first animals
• to venture on to land. They
• emerged from the oceans over 300
• million years ago.

AMPHIBIANS

• They are special because the early
• stages of their lives are very
• different to the adult stages.
• The young amphibians are called
• tadpoles and they have tails and no
• legs. The adults have four legs and
• only some of them have tails.
• They all have smooth skins with no
• hair or scales.
• Amphibians generally need a lot of
• humidity in order to survive

FISH

• They are cold blooded and
• aquatic animals.
• Fish use gills to obtain
• oxygen. The gills are behind
• the head.
• Fish live in both fresh and
• salt water and can be found
• all over the world, except in
• some very hot springs and
• the Dead Sea because it is
• too salty.

FISH

• Fish are oviparous animals.
• The females lay their eggs in
• water.
• The young emerge from the
• eggs, they are called fry.
• Fish are animals which have
• scales and fins located in the
• thorax, stomach, back and
• tail.
