Cnidarians
Cnidaria, also cnidarian, is a phylum found in aquatic and marine environment. These invertebrates include jellyfish, sea anemones, some corals, and sea fans. One interest cnidarian is the praya dubia. The praya dubia can stretch up to 40 meters. The predators of cnidarians are marine turtles, their bodies consist of mesoglea, a jelly like substance. Cnidarians eat planktonic animals that they catch with either their tentacles or stinging nematocysts. Instead of trying to catch their food, cnidarians must wait for food to come right into their tentacles. Since these cnidaria do not have heads, each end is referred to as either oral, nearest to the mouth, or aboral, farthest from the mouth.
