Centipedes and Millipedes
Centipedes are made up of 30 segments, each containing one pair of legs.
They have chewing mouthparts. Some species can inflict painful bites on
humans.

Millipedes contain 30 segments and are cylindrical like an earthworm.
The body is wingless and each segment bears two pairs of legs. The antennae
are short, and mouthparts are comblike. Millipedes feed on decaying organic
matter, seeds, bulbs, and roots.
There is no metamorphosis: centipedes and millipedes do not change ex-
cept in size between hatching and reaching the adult stage.
