Earthworm Anatomy Lab. Practical

Welcome to the electronic biology classroom of the 21st century. This laboratory practical is based upon earthworms (Lumbricus terrestris) which are representative animals of phylum Annelida. You will be tested on the external and internal structures, organs, and annelid characteristics. Your answers are lower case sensitive for all tests constructed by Pulsar_Lincoln instructor. Good Luck and earn a high grade on the laboratory practical.
