At about 2,230 meters (~7,315 feet) during Dive 13, we observed benthic ctenophores attached to the bottom of a glass sponge. The filamentous tentacles extended from the organism’s tube-like tentacle sheaths. Ctenophores are commonly seen in the water column, but this is an order that has adapted to live on other organisms. Benthic ctenophores were quite common in the Pacific, but they aren’t observed as frequently in the Gulf of Mexico.
