Good to know

Six things about the giant millipede

Long

One of the longest

It can grow to more than thirty centimetres, making it one of the largest millipedes alive.

Legs

About 250 legs

Despite the name, no millipede has a thousand legs. This one has around 250.

Coil

It rolls into a coil

If frightened it curls into a tight spiral, with its head safe in the middle.

Stink

A chemical defence

It oozes a liquid from pores along its sides that stains skin and tastes foul.

Mites

It carries its own cleaners

Tiny mites live on its body and keep it clean. They do it no harm.

Slow

A gentle giant

It eats only rotting leaves and wood, and cannot bite or sting.

Out and about

How to spot one

Look on the forest floor after rain, when they come out to walk. The slow ripple of the legs is easy to follow.

Lend a hand

How to help

Millipedes turn dead leaves back into soil. They are often kept as pets, and should never be released where they do not belong.
