Type an “x” where the feature occurs in the specified phyla:Radial symmetry(or asymmetry)Bilateral symmetryTissueBody cavity SegmentationComplete digestive tractEndoskeletonExoskeletonSponges(Porifera)XXCnidarians(Cnidaria)XXXXFlatworms(Platyhelminthes)XXXRoundworms(Nematoda)XXXXXAnnelids (Annelida)XXXXMollusks(Mollusca)XXXXXXArthropods-arachnidsXXXXXXArthropods-crustaceansXXXXXXArthropods-insectsXXXXXXArthropods-millipedes, centipedesXXXXXXEchinoderms(Echinodermata)XXXXXX2.Search online for images of species for each station. For each invertebrate include the following information:a.Image and sourceb.At least two features or visible structures that are specific to that group and not found in other groups
