The fertilised eggs develop directly into young worms, which then escape through the egg membrane and eat the nourishing albumen contained in the cocoon. This method of feeding does not require highly developed sense organs (such as eyes, which would be of little use underground) or food-catching structures, and earthworms never possess the often very remarkable and versatile head appendages developed in some of the free-swimming, carnivorous marine polychaete worms. Suppose you have collected a greenish tinged earthworm from a muddy garden.

These organisms live in and feed off a living host, like a human. Food is then digested by juices secreted by gland cells in the intestine. Regular worming is so important. These are the calciferous glands that excrete calcium carbonate to dispose of excess calcium obtained in the food.
