Ocean Soup in the "undisturbed" waters off SE North Carolina:
Out here these animals are the ordinary inhabitants, and we are the curious looking aliens.
I've called these beroids or beroid ctenophores. They are a family within the Phylum Ctenophora known more commonly as Comb Jellies. Beroids lack the tentacles found in comb jellies but, like comb jellies propel themselves through the seas with luminescent cilia set along prominent longitudinal ribs. Look closely, and the flashing luminescence can be seen; most notably on the left marginal rib in the second picture. The lateral zipper-looking line is the animal's mouth, and when feeding will gape open to swallow prey whole. All the white and blue dots in the water column are planktonic organisms and possibly a potential meal for the beroid. It also appears the beroid has severely damaged tissue along its left side. This beroid is round 12cm/5 in. in length and if it continues to survive wounds and dodge predators may grow to 30cm/12in.
It reminds me of automobile designs when I was a kid. ; )
