Some deep-sea fireworks, in the form of a Rhopalonematid jelly (Crossota millsae)! Imaged in a very interesting natural pose by the remotely operated vehicle Deep Discoverer’s cameras in waters south of La Parguera on the southwestern shore of Puerto Rico at a depth of 1,015 meters (3,330 feet).
Known from the Atlantic as well as the Pacific, jellies similar to these have been found not too far from the seafloor, suggesting a linkage between the benthos and the water column. Recording seemingly natural behaviors and stances by deep-ocean life in high-definition has given us the ability to not only identify these organisms, but learn a little about how they live.
