These coelenterates are usually sack-shaped and 

 may be either individual or colonial. Sea anemones 

 are usually solitary and attach themselves to some 

 hard object by means of a broad adhesive pedal disc. 

 They are, however, not permanently attached and 

 may move about as they please. They have a crown 

 of tentacles, usually bearing nematocysts or stinging 

 cells. Many sea anemones are very beautiful and of 

 considerable size — truly flowers of the sea. They 

 do not have a hard skeleton.
