Does the earthworm have a nervous system?

The earthworm has a nervous system that is segmented like the rest of its body. The brain is found above the pharynx, and it is important for movement. Without the brain, the earthworm would constantly move.

There are 2,700 different species of earthworms. They have no arms, legs or eyes. Even without eyes, earthworms can sense light and can become paralyzed if exposed for too long. They are cold-blooded animals, and they can replicate lost segments, depending on the species of worm and the amount of damage. Earthworms have both male and female organs. This makes them hermaphrodites. Baby earthworms hatch from cocoons.
