Blood Belly Comb Jelly

Great video of a comb jelly with its silica plates that are reflecting light.  These plates are aligned in rows or combs and thus the name.  Comb jellies are not jellyfish.  The two are in different phyla, Ctenophora and Cnidaria.  The main difference is that Cnidarians have stinging cells and Ctenophores have the silica plates.
