not what those guys said
Setae are bristles or hair-like structures that help attach the earthworm to the ground and create friction so if an earthworm is going down a hill, it would slide down but actually continue to move through hydrostatic pressure.
The bristles along the body of an earthworm are called the Setae,which are set along its segmented length. In all the body segments except the first, last and clitellum, there is a ring of S-shaped setae embedded in the epidermal pit of each segment.
The first segment on an earthworm is called the prostomium. It is a fleshy lobe that covers the mouth and helps the earthworm sense its environment.
