This pelagic holothurian, or deep-sea swimming cucumber, is unusual in appearance when compared with other sea cucumbers because of its resemblance to a jellyfish. We found this one during midwater transects at ~1,400 meters (4,595 feet) depth. We have seen many of these sea cucumbers so far on this expedition.
