About Comb Jelly :
* It is any of the numerous marine invertebrates constituting the phylum Ctenophora.
* It is a beautiful, oval-shaped animal with eight rows of tiny comblike plates that it beats to move itself through the water.
* As it swims, the comb rows break up (diffract) light to produce a shimmering rainbow effect.
* Some ctenophores live in somewhat brackish water, but all are confined to marine habitats.
* They live in almost all ocean regions, particularly in surface waters near shores.
* They are frequently swept into vast swarms, especially in bays, lagoons, and other coastal waters.
* They are carnivorous, eating myriads of small planktonic animals..
