I went snorkeling in Kettle Cove today and managed to get this picture of a ctenophore:
You can clearly see the rows of reflective cilia called "ctenes" that give the phylum it's name. You can also see one of the tentacles dangling down to the left. It uses these sticky threads to entangle zooplankton. The stomach is in the middle of the ball, and the bald thing with the snorkel is me. I'm not a jelly expert, but I'm pretty sure this guy is Pleurobrachia, a known copepod predator.
Way better than any of our LOPC images. We should deploy more bald-snorkel-devices. Great picture. How big was it?
The ctenophore was about the size of a ping pong ball. If you think the LOPC is cranky, wait til you try working with a bald snorkel device.
Well, the LOPC is cranky, but it might've captured a few ctenophores itself: http://www.seascapemodeling.org/lopc/2010/08/ctenophores.html
