Six things about the earthworm

Soil

Making soil

Worms drag dead leaves underground and eat them. What comes out the other end, the worm cast, is rich food for plants.

Tunnels

Air and water

Their burrows let air and rain down into the soil, which helps roots to grow.

Moving

Squeeze and stretch

A worm moves by making itself long and thin, then short and fat. Tiny bristles on each ring grip the soil.

Senses

No eyes, no ears

Worms have no eyes or ears, but their skin can sense light and feel the slightest vibration.

Breathing

Breathing through skin

A worm breathes through its damp skin, which is why it dies if it dries out in the sun.

Saddle

The saddle

The pale band near the front of an adult worm is called the saddle. It makes the cocoon that the eggs are laid in.

How to spot one

Look on the lawn on a mild, damp night with a torch covered in red plastic, and you may see them stretched out of their burrows. Or just dig.

Lend a hand

How to help

Mulch with compost or leaf mould rather than digging, and avoid lawn chemicals. Leave fallen leaves on borders for them to pull down.
