Coelomate Animals: Here we can study the museum specimens of celomate animals their classification and characteristic. Coelomate animals are those that possess a true coelom, a fluid-filled body cavity completely lined by mesodermal tissue. This group includes a wide variety of animals, from simple invertebrates (Mollusks, Annelids, Arthropods and Echniodermata) to complex vertebrate (Chordata) animals….
