Dissection of a Worm Purpose: We will do a dissection of a lumbricus terrestris. We will observe the structures of the earthworm, how the earthworm?s body is adapted to living in the soil, and how an earthworm demonstrates cephalization. Materials: One specimen of Lumbricus terrestris Rubber gloves Dissection kit Dissection tray Pins Procedure: Pin the worm to the dissection tray Using a scalpel, make a light incision at the dorsal side of the clitellum Using forceps and a probe, spread the incision open, little by little Pin down each piece of loose skin as you open the incision When you are done observing the specimen place it in a plastic bag for proper disposal by your instructor Clean up your work area and wash your hands before leaving the lab
