Centipedes are made up of many tiny segments, with one pair of legs attached to each segment.
The first segment behind the head and the last two do not have any legs attached,
but the the first segment behind the head has fangs that are modified appendages, and aid in capturing prey.
Centipedes are predatory, eating mostly small invertebrates.
All centipede species are terrestrial, but they must have a moist environment.
There are over 2500 species of centipedes in the world.
