The living world

There are many creepy crawlies


scuttling around our planet that


are not insects. Some live on


land, others live in fresh water


or the sea. They come in all sorts


of weird and wonderful shapes.


The worm family
Segmented worms like
earthworms are simple
animals that have a
head at one end, a tail
at the other, and lots of
segmented body parts
in between. They live
on land or in water.

Arachnids


Spiders, scorpions, ticks, and mites belong


to a land-dwelling family called arachnids.


All arachnids have eight legs and two


body parts.


A tarantula has
hairs on its legs
that can cause
bad irritation.
When the
spider is
annoyed, it
flicks them out
at the enemy.

Despite their reputation, most
spiders are harmless to humans.
