Lifestyle and structural features of annelids (for example, an earthworm)

The earthworm lives in moist, humus-rich soil.
On the first third of the body there is a girdle that secretes mucus, into which the eggs of the semen worm fall during the movement of the sleeve towards the head end of the body. The clutch slides off, a cocoon is formed, inside which young individuals develop. Also, earthworms have the ability to regenerate, and have the ability to improve soil fertility.
The head lobe in the worm is not pronounced, devoid of eyes, tentacles, antennae. There are bristles on the walls of the body that serve for movement. The ducts of the calcareous glands open into the esophagus, the task of which is to remove the humic acids of the soil.
