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.
