Ecdysozoans are protostomes. They get their name from the fact that they all secrete a nonliving exoskeleton that requires molting in order to grow. The ecdysozoans include the invertebrate phylum Nematoda, such as roundworms, and the invertebrate phylum Arthropoda, such as insects and crustaceans.

Classify each description into the correct animal group: Annelids - Segmented bodies, do not possess coelom and periodically molt. Echinoderms - Possess coelom and periodically molt, have jointed appendages and hard exoskeleton. Cnidarians - Jellyfish that contain stinging cells. Liver fluke - Flatworms. Roundworms - Nematodes. Platyhelminthes - Flatworms. Arthropods - Insects, crustaceans, and arachnids. Mollusks - Snails, clams, and octopuses. Protozoa - Single-celled organisms. Sponges - Porifera.

Drag each description on the left to the animal phylum on the right with which it is most closely associated. Chordates: scorpion, sea turtle Echinoderms: animals with radial symmetry, water vascular system aids movement Cnidarians: sea anemones Arthropods: have an exoskeleton and jointed appendages Annelids: segmented worms with pseudocoelom Porifera: sponges Nematodes: roundworms Platyhelminthes: flatworms Title_with_topic: Animal Phyla and Associated Descriptions
