Myriapoda

From Wikipedia:
Millipedes, centipedes etc belong to the family of Myriapoda. They range from having over 750 legs ro having fewer than 10 legs. They have a single pair of antennae and simple eyes.

Myriapods are most abundant in moist forest, where they fulfil an important role in breaking down decaying plant material, although a few live in grasslands, semi-arid habitats or even deserts.

The majority are herbivorous, with the exception of centipedes, which are chiefly nocturnal predators.
