The comb jellies were recorded two and a half miles below sea level using NOAA's Deep Discoverer remotely operated vehicle. The new species and a new virtual method of describing and documenting the discovery are both explained in Plankton and Benthos Research. Most comb jellies have eight rows of comb-like cilia that rhythmically beat, refracting light into colors, as they paddle through the water. Between — species of comb jellies have been identified and validated. They are all carnivores and many are highly efficient predators that eat small arthropods and many kinds of larvae.
Although they look similar, comb jellies and jellyfish are not closely related. Deep Discoverer , a remotely operated vehicle ROV captured high-definition video of the new ctenophore species during a dive off the coast of Puerto Rico.
This marks the first time NOAA scientists exclusively used high-definition video to describe and annotate a new creature. Watch video of the first encounter with the newly discovered ctenophore:. The cameras on the Deep Discoverer robot are able to get high-resolution images and measure structures less than a millimeter. During their exploration, the scientists made three video observations of the comb jelly from their shoreside control room. We went through the historical knowledge of ctenophores and it seemed clear this was a new species and genus as well.
We then worked to place it in the tree of life properly. It was a really good example of how to do it the right way with video. Based on the video evidence, the scientists observed some fascinating behavior. We did not observe direct attachment during the dive, but it seems like the organism touches the seafloor. The scientists saw the specimens just long enough to get a visual look and describe the species, but their unknown ecological role is exciting to contemplate.
