Solution :-

There are three types of nephridia present on earthworms.

(i) Septal nephridia: It is located behind the 15th segment and is present on both sides of the intersegmental septa. As it is present from 15 to the last segment therefore it opens into the intestine.

(ii) Integumentary nephridia: These are attached to the body wall lining from the third segment to the last segment which opens on the body surface.

(iii) Pharyngeal nephridia: These nephridia are present on the sixth segment in the paired form of three tufts in the fourth, fifth, and sixth segments.
