Three of these wonderful animals were seen near the bottom on Dive 1 at about 4000 meters. With eight rows of ciliated combs along the bottom of the body, and very long tentacles originating from thick tentacle sheaths make this an unusual find. A similar animal was seen on a ROV dive over the Mid-Atlantic Ridge in 2010.
