The earthworm is a tube-forming and segmented form in theAnnelida photograph. They are generally found living on the ground, feeding on life and death. The system begins through its long body. Earthworms respirate through the skin. Earthworms have a dual transport system consisting of liquid moving cells in liquid-filled and circulatory-enclosed circuits. It has central and peripheral nervous system. The central nervous system consists of two upper mouth ganglia, one on either side, connected to a neural rope running back along the length of the motor neurons and sensory cells in each segment. A large number of chemoreceptors are concentrated near his mouth. The circular and longitudinal muscles on the periphery of each segment allow the worms to move. The same set of intestinal line muscles, and their actions move the food digested into the worm's anus. [2]
Earthworms are thehermaphrodites - each individual carries both male and female sex organs. They do not have an internal or ekeloskeleton, but retain their structure with a liquid chamber that functions as a hydrostatic liquid. "Earthworm" is the common name for the largest member of Oligochaeta (which is a class or upakelas depending on the author). In the classical system, they are placed in an order of Opisthopora, on the basis of male pores membostering the pores into the female pores, although the anterior male segment is anterior to the female. Studikladistikteoretis has placed them, on the contrary, in the suborder of Lumbricina from the order Haplotaxida, but this may again soon change. Larger ground worms are also called megadriles (or large worms), as opposed to microdriles (or small worms) in the semicircic families Tubificidae, Lumbriculidae, and Enchytraeidae, among others. Megadriles are characterized by having different clusters (wider than microdriles) and vascular systems with true capillaries. Earthworms are much more abundant in uninterrupted environments and are usually active only if water is present
