Do Earthworms have Eyes and can they See, or are they as Blind as a Bat?

Earthworms have no eyes, but they can sense light and dark.

Earthworm is the common name for the largest members of Oligochaeta, and is also known as “dew-worm”, “rainworm”, “night crawler” and “angleworm”.

Earthworms are hermaphrodites and can live up to 8 years, but normally live for about 2 years in the average garden.

Locomotion by earthworms is achieved by waves of muscular contractions which alternately shorten and lengthen the body.

In many environments, earthworms play an important role in converting large pieces of organic matter like dead leaves into rich humus, and thus improving soil fertility.
