What's a ctenophore?

Last week we examined cnidarians in lab.  Another animal phylum traditionally thought to be closely related to corals, anemones and sea jellies are the comb jellies, or ctenophores.  What is a ctenophore?  Check out the video from the CreatureCast:

While many textbooks state that combjellies and sea jellies are sister taxa (each other's closest relative), current work suggests that they are more distantly related.
