Scientists announced that they exposed a new ctenophore species, or comp jelly, near Puerto Rico.
According to CNN, the Duobrachium sparsae was found two and a half miles below sea level by the National Oceanic and Atmospheric Administration Fisheries research team. In 2015, researchers used a remotely operated vehicle and filmed the creatures with a high-definition camera during an underwater expedition.
NOAA Fisheries scientists Mike Ford and Allen Collins saw the ctenophore and identified a new specifies using high-definition video.
"The cameras on the Deep Discoverer robot are able to get high-resolution images and measure structures less than a millimeter," Collins said. "We don't have the same microscopes as we would in a lab, but the video can give us enough information to understand the morphology in detail, such as the location of their reproductive parts and other aspects."
During the research, the scientists said they could not gather any samples, so the video footage is the only evidence that they have.
"Naming of organisms is guided by international code, but some changes have allowed descriptions of new species based on video — certainly when species are rare and when collection is impossible," Ford said. "When we made these observations, we were 4,000 meters down, using a remote vehicle, and we did not have the capabilities to take a sample."
According to the NOAA, the new species are not related to jellyfish, and scientists have found between 100 to 150 species of comb jellies.
The public can now see the videos publicly at the Smithsonian National Museum of Natural History Collection.
