Assess students' ability to recall and identify the major animal phyla (e.g., Porifera, Cnidaria, Platyhelminthes, Nematoda, Annelida, Mollusca, Arthropoda, Echinodermata, Chordata) and their defining characteristics — including body symmetry, tissue layers, coelom type, segmentation, organ systems, and representative examples; include item types that require naming phyla from descriptions, matching traits to phyla, and selecting correct examples.
