Under Your Feet

SPINELESS

INVERTEBRATES

Animals without backbones make up

90 per cent of all creatures on Earth.

These are called invertebrates, and the

ground is crawling with them.

Velvet worms

The soft texture of these

creepy-crawlies gives them

their name. They look like

worms but have

lots of legs.

Molluscs

Molluscs move around on a large,

slimy foot. Most molluscs have shells.

Snails have shells that they live

in. They use their shell to

hide from predators.

Each leg has

a tiny pair

of claws.
