An earthworm is a soil-dwelling terrestrial invertebrate that belongs to the phylum Annelida.The term is the common name for the largest members of the class (or subclass, depending on the author) Oligochaeta.In classical systems, they were in the order of Opisthopora since the male pores opened posterior to the female pores, although the internal male segments are anterior to the female.

Earthworm Anatomy

The earthworm body is divided into ringlike segments (as many as 150 in L. terrestris).Some internal organs, including the excretory organs, are duplicated in each segment. Between segments 32 and 37 is the clitellum, a slightly bulged, discoloured organ that produces a cocoon for enclosing the earthworm's eggs.The body is tapered at both ends, with the tail end the blunter of the two.

Life cycle of an earthworm Earthworm Society of Britain

Worm Anatomy. A worms body is made up of many segments called 'annuli'. The length of a worms body has muscles which contract and relax which enables the worm to move along a surface. The 'annuli' are covered in tiny hairs called 'setae' which help the worms movement. Worms have no lungs, so they do not breathe like a human being or.

Earthworm

Worms are invertebrate animals with bilateral symmetry. Worms have a definite anterior (head) end and a posterior (tail) end. The ventral surface of worms and other organisms is the bottom side of the body, often closest to the ground. The dorsal surface is located on the upper part of the body facing the sky. The lateral surfaces are found on the left and right sides of the body.
