A Comb Jelly

Ran into this little guy while coming up from a wreck dive. They are know as comb jellies or Ctenophores. Although they look like jellyfish, they are actually in a completely different category of creatures. The major difference between these guys and jellyfish is that this one will not sting you. Ctenophores also display spectacular colors via their iridescent pulsing combs (located along the side of their bodies).
Unfortunately for this guy, a green sea turtle swam by moments after this shot was taken and ate him (how was the turtle able to spot this translucent creature from a distance in the big wide ocean... I don't know). Witnessing this made me realize how vulnerable sea turtles are to eating plastic bags and other similar looking non-biodegradable rubbish floating around in the ocean. Let's be careful to keep are oceans clean.
Aloha!
