nephridia
The excretory system of a worm is comprised of three pairs nephridia. Each type of nephridia, the integumentary, septal, and pharyngeal, is located in a different segment.

Pair of nephridia in earthworm's segments excretes waste through pores in the skin, removing waste from the blood and body fluids.
nephridia
Grasshoppers eliminate their nitrogenous waste through the malipighian tubules that are on the digestive tract. Earthworms eliminate their nitrogenous waste by the nephridia.
Earthworms respire and take in oxygen directly from the skin. Perspiration, sweating, happens with holes called nephridia that let out the sweat from the body. In the fall, earthworms go below the frost-line to migrate. They also hibernate down in the soil around six feet deep.
Nephridia!!!!!actually nephridia are the units that filter to make the waste, somewhat similar to our kidneys, the waste they excrete is urea, not ammonia (highly toxic, not good for its body to be surrounded by) and it isn't uric acid either which is usually made to conserve water--an earthworm surrounded in a moist environment doesn't need to conserve all that much water. Or poo.
In an earthworm, nephridia occur in all body segments except the first three segments. Integumentary nephridia are V-shaped and lack nephrostomes.
