Narcomedusae, Bathykorus bouilloni (Aeginidae), The new jellyfish is in the order Narcomedusae. It has four tentacles, 12 stomach pouches, and most interestingly, four small secondary tentacles at the very edge of the bell. While foraging for food, this species holds its long tentacles, covered with poison filled stinging cells, out in front while it swims, perhaps to ambush its prey more effectively.
