The living world


Mammals include animals such as the


whale, the kangaroo, and you and me!


We all have fur, we are warm blooded,


and we feed new babies with our milk.


Feeding babies
All female mammals produce
milk from their bodies that
they feed to their babies; this
feeding is called suckling.
The milk is rich
and helps
the babies
to grow.

The skeleton
Mammals may
look very different,
but stripped back
to the bone we all
have the basic bony
skeleton. Scientists
call us vertebrates


  • animals with
    a backbone.


Mammal babies


Most mammal females give birth


to live babies, rather than laying


eggs. The baby grows inside


the mother’s


body until


it is born.


Within the
mammal group
there are many
different families.

This baby
gorilla is a
member of the
primate family.
