Everything needed to know about worms... And then some!
The ideal earthworm habitat is moist fertile soil. Some special habitats that an earthworm might live in is decaying plant life or dead leaves. Also many earthworms live in manure. Earthworms are even found in decaying conifer logs. Some earthworms live in acidic soil, but most do not because it is not good for the worms. The more acidic soil the worms would eat would eventually kill said worm.
There are three types of earthworms. Anecic is the largest type of earthworm, these worms are slightly pigmented. Anecic worms dig the deepest of all of the earthworms. The second type of earthworm is Endogenic. Endogenic worms are the ones that feed the soil the most and make it fertile. These worms are not pigmented and only dwell in topsoil. The final type of worm is Epigeic. Epigeic worms dwell on top of the soil. They are fully pigmented and they consume the litter on top of the soil. Different types of worms have adapted to their environment. Each worm has their own niche. Some niches of worms are that they can excrete mucus so they can slide more easily through their burrow. Another adaptation is that some worms can change their body temperature by covering their body in a mucus film.
C. Life style
Earthworms basically live out their lives blindly inching their way through soil. Worms greatly impact the environment because the soil that they process through their body helps fertilize the soil and helps plants grow. Worms breathe just like humans, but worms respirate through their skin. Worms can detect vibrations in the ground so that they know where to go. Worms have light receptors which can tell if it is light or dark. Worms get nutrients by filtering soil through their body. Worms mouths are very muscular to make up for the lack of teeth.
