Annelid Biology Concepts

Mr. Gripper introduces a new unit on phylum Annelida, discussing the classification and general characteristics of annelids, including their segmentation, internal structure, and systems such as excretory, circulatory, and nervous systems. The video concludes with instructions for students to complete an exit slip on Schoology.
