Earthworm MCQs and Answers: About Earthworm

The earthworm is a common name for the largest members of Oligochaeta (which is either a class or subclass depending on the author) in the phylum Annelida. In classical systems, they were placed in the order Opisthopora, on the basis of the male pores opening behind the female pores, even though the internal male segments are anterior to the female. The pereiopods or parapodia are uniramous and there are neither palps nor pygidia.

Earthworms are commonly found living in soil, feeding on live and dead organic matter. An earthworm’s digestive system runs through the length of its body. It conducts respiration through its skin. It has a double transport system (blood vessel and coelom) that also puts it into the category ‘Vertebrata’.

Earthworms are hermaphrodites (each worm has both male and female reproductive organs). When two worms meet, they exchange sperm before separating. Each worm then lays a cocoon, which it fills with eggs. The cocoons hatch after about three weeks, releasing newborn worms that grow to adulthood in about three months.
