This ctenophore, seen during Dive 1, is characterized by its jet black pigmentation. This animal appears to be similar in form to species found closer to the coast; this one sets itself apart with pigmentation and a long tentacle. Only one tentacle is seen in this image, and it is not clear whether a second tentacle was lost.
