This document provides information about various phyla and classes studied in Zoology Lab Exam II. It includes detailed diagrams and descriptions of key anatomical features of sponges (Phylum Porifera), jellyfish and hydras (Phylum Cnidaria), flatworms (Phylum Platyhelminthes), mollusks like snails, clams, and octopuses (Phylum Mollusca), and armored slugs (Class Polyplacophora). The document aims to familiarize students with the major organ systems, tissues, and identifying characteristics of many marine invertebrate groups.
