Imagine you come across a colonial organism. Determine whether it is a class Hydrozoan or a anthrozoan? Give two distinct differences between the two without naming the same structure/invisible features of each animal (e.g animal x has 2 wings, animal y has 4 wings are not distinct differences)

You take a field trip to tide pools in Puget Sound and encounter all sorts of Animals. Please use the following descriptions of those adult Animals to determine which of the 9 major phyla each belongs. 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"]  Has no true tissues and no body symmetry: ["cnidaria", "Mollusca", "Arthropoda", "Nematoda", "Platyhelminthes", "Porifera"]

Your instructor has a preserved organism behind her back. She gives you the following clues as to its identity. It is an animal but it contains fewer than 2 germ cell layers (primary tissue layers). Furthermore, it does not have any kind of symmetry. It must be a   Question 8 options:   a)  flatworm.   b)  starfish.   c)  sponge.   d)  jellyfish.
