Cnindaria
Cnindarians are made primarily of a lifeless jelly-like substance. They are carnivorous marine animals. They are either structured as polyps, such as sea anemones or coral, or free-floating medusae, such as jellyfish. Polyps have a tube-like body with an opening on top that is surrounded by outward- and upward-facing tentacles. Medusae are bell-shaped animals with a concave mouth and tentacles that dangle downward from the rim of an umbrella-like body.
