NEW FILM: Luminescent Sea Salps

These salps were filmed in Gloucester’s inner harbor and had a luminous appearance in the blue lights of the fishing boat Hot Tuna, the largest boat in the Wicked Tuna fleet. I think the song “La Luna” by Lucy Schwartz adds to the magical movement of the salps and other creatures in the glowing blue. (So sorry to Captain Ott for startling him while hanging over the edge of the dock to film the salps at the rear of his boat, and Hey to Nicky Avelis!)

Sea salps are warm ocean water creatures, exploding in population during algae blooms. With beating heart, notochcord, and gills they are more closely evolutionarily linked to humans than to jellyfish. Sea salps are individual creatures that through asexual reproduction, can form linear chains up to fifteen feet long!

Salps are planktonic (free floating) members of the subphylum Tunicata. Tunicates get their name from the unique outer covering or “tunic,” which acts as an exoskeleton. The sea salp’s tunic is translucent and gelatinous; in some species it is tough and thick.

  2. Beautiful Kim, thanks for making this for us!
    What a wild experience to swim with them on a sunny day. As I floated through millions of these jellies, daylight streamed through their transparent bodies. I could see the ocean floor through them..what a treat!
