clitellum

Earthworm reproductive girdle

The clitellum is a thickened band or saddle-shaped region on an earthworm's body, usually lighter in color than the surrounding segments.

It secretes mucus that forms a cocoon for eggs during reproduction.

The presence of a visible clitellum indicates a sexually mature worm.
