Ctenophora - Comb Jellies

There are over 100 species of comb jelly, and most are transparent planktonic predators. They swim feebly by beating rows of plates made from fused hair-like cilia (the 'combs') and catch their prey with dangling tentacles.

•The tentacles usually have 'colloblasts' on them which help the tentacles stick to the animals they touch. (Colloblasts are single cells that give off a gluey substance when touched.)

•One type of comb jelly feeds on true jellyfish and is able to use the stinging cells (cnidocytes) on its tentacles, in much the same way as some of the sea slugs.
