Cnidarians come in two forms: a medusa has tentacles that hang down and polyps usually live attached to a surface.
Polyp and medusa are two stages in life cycle of cnidarians , polyp is hydra like and medusa is jelly fish like .
Polyps, which are Sessile or stationary, and Medusa which move.
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 have two cell layers with a jelly-like layer in between.
They are called nematocytes. They are one of at least three types of cnidocytes, the very definition of the phylum. Nematocytes sting, the other two types of cnidocytes either adhere, or gum up their prey, substrate, or that guy that wears a helmet and does super glue commercials.
