No, the body of an earthworm is composed of segments. The broad bands around the body are called saddle stripes. There are photoreceptor cells everywhere on the surface of the earthworm's body.

Earthworm is one of the annelids. There are more than 3,000 species of earthworms in the world, and there are more than 200 species in my country. Widely distributed across the country are Trichosanthes, Eisenia, Heterochaetes, Dura and other species.

Respiration:

Respiration occurs through the diffusion of gases on the body surface. Earthworms do not have respiratory organs, but because there is a large number of capillary networks distributed on the body surface, they can easily exchange gases when the skin is moist. There is abundant hemoglobin dissolved in the plasma of earthworms, and hemoglobin can easily combine with oxygen and release oxygen. It has been reported that 40% of the oxygen used by earthworms is delivered by hemoglobin in plasma.
