For the teacher who understands the importance of using quality, detailed models to support their lessons, but doesn’t want to mortgage the lab in order to acquire one - this well-made, economy Earthworm Anatomy model is the way to go. Of special note: this model is of the earthworm family Pheretima rather than the more common Lumbricus. External structures shown include: segments, intersegmental grooves, clitellum, peristomium, female pore, male pores, and spermathecal orifices. Internal structures shown include: body wall, muscles, septa, coelom, digestive system, circulatory system, female and male productive systems, and nervous system.
