Look at this totally amazing footage of one comb jelly eating another - I've known for years that it happens, and told hundreds of people about the phenomenon, but never seen it in action so to speak. Comb jellies are some of the larger forms of animal plankton (some can grow up to 15cm long) - we get them in the seas around Britain, so keep your eyes peeled, you never know! Liza.
