SESE Living Things
Reproduction
The life cycle
All animals, including
humans, start out as babies
and get older.
When babies are born
they are very small.
Some animals need
their parents to protect
them and to help them
learn about the world.

The life cycle
As animals get older they
can start to do more things
by themselves.
They will become bigger and
stronger and more able to
look after themselves.
Seal pup with its mother
The life cycle
Once an animal is fully
grown it will find a mate.
Together they will have
their own babies and the
cycle will start again.
They will continue to grow
old and the cycle will end
when they die.
Baby turtle
The adult penguin
lays an egg and looks
after it until it hatches.
The egg hatches.
The penguin chick has
fluffy feathers and is
looked after by its parents.
The chick is a fully
grown adult. It can
catch all of its own food.
The chick grows bigger.
Its feathers become
thick and oily.
Reproduction
Different types of animals
reproduce in different ways.
All animals need a male and a

Clownfish can change from male
to female, if a female in their
group dies.

Reproduction
Humans, which are mammals,
give birth to live babies.
Babies grow inside the mother
before they are born.
Seals, whales and otters are all
also mammals.
Baby seals are often rescued
by SEA LIFE after they lose
their mothers.
Reproduction
Fish, birds and reptiles all lay
eggs.
The baby grows in the egg and
hatches when it becomes big
enough.
Crocodiles, turtles and snakes
are all reptiles.
