Examine the diversity, life cycles, and anatomical adaptations of invertebrate and vertebrate animal groups (cnidarians, flatworms, nematodes, annelids, arthropods, mollusks, fish, amphibians, reptiles, birds, mammals); classify animals by diet (herbivores, carnivores, omnivores); and compare thermoregulation mechanisms (endothermy and ectothermy).
