Has radial symmetry and two tissue layers: ["cnidaria", "Mollusca", "Arthropoda", "Annelida", "Platyhelminthes", "Porifera"]
Has 6 jointed appendages and a chitinous exoskeleton: ["cnidaria", "Mollusca", "Arthropoda", "Annelida", "Platyhelminthes", "Porifera"]
Has bilateral symmetry with a digestive sac and no coelom: ["cnidaria", "Mollusca", "Arthropoda", "Nematoda", "Platyhelminthes", "Porifera"]
Has bilateral symmetry, an open circulatory system, a digestive tube, gills and a radula: ["cnidaria", "Mollusca", "Arthropoda", "Nematoda", "Platyhelminthes", "Porifera"]
