Describe the signs of the earthworm’s adaptability to life in the soil environment.

Earthworms are hermaphrodites. This is so that two worms can mate when they meet, regardless of gender.
In earthworms, visual analyzers are completely absent, although they would only interfere with the worm, given where it lives.
Mucus is secreted from the body of the earthworm, with the help of which it is much easier for the worm to move in dense earth.
The shape of the body of the earthworm and the way its muscular apparatus is arranged help it very well to move in the thickness of the earth.
The earthworm has a very well developed olfactory analyzer.
