5. Reproduction MethodReproduction Method
Both the centipede and millipede have separate sexes.
The female lays eggs which are fertilized sexually by the male.

eating dead vegetation.
•Centipedes are carnivores. Their
first pair of legs inject venom to kill
prey. They feed on insects,
earthworms, and slugs. They also
eat dead vegetation.
•The digestive system is a gut that
runs from the mouth to the anus.
•The gut is lined with a protective
outer covering called a chitin, that
is shed every so often.
