A Cnidarian is a stinging animal such as a jellyfish or a sea anenome. They have stinging cells that they use predatorially for food. There are two body scructures for cnidarians--polyps and medusas. A polyp is attached to something and does not move, and its mouth is at the top. A medusa is free-swimming, and its mouth is on the bottom.
No. Cnidarians do not have teeth or any hard body parts.

The body systems that cnidarians have take two forms. The main body forms are medusa and polyp. Cnidarians do not have a transport system and the body surface is used for gaseous exchange.

Cnidarians exhibit radial symmetry, which means their body parts radiate out from a central point. This symmetry allows cnidarians to capture prey efficiently from all directions.
alot of people don't know!
The study of the parts of the human body and their functions is called anatomy and physiology. Anatomy focuses on the structure and organization of body parts, while physiology explores how these parts work together to carry out various functions necessary for life.

Yes. They are are the first phylum to display cell organization into tissues and the second to desplay radial symmetry.
