What is Earthworm?
Earthworms are reddish-brown, segmented terrestrial invertebrates that live in moist soil. They are the largest members of the Oligochaeta class and belong to the phylum Annelida. They have a streamlined body with no antennae, fins, arms, or legs. Earthworms feed on organic matter, breaking it down into nutrients that enrich the soil and support plant growth. They lack lungs but respire through their skin, which must remain moist.
They have both male and female reproductive organs hence called hermaphrodites. They are also known as farmer’s friends because they increase soil fertility by thier worm castings (or faecal deposits) and their burrowing helps aerate the soil.
