Cnidarians
The Cnidaria phylum consists of over 10,000 species including Jellyfish, Coral, and Hydroids. A significant thing about the Cnidaria is that they have their mouth and Anus as the same hole. They also have specialized dlls that they used to capture, kill, or paralyze their prey. An example of these cells are how the Jellyfish have their stingers to help them capture their prey.
