For a team of federal researchers looking for geologic data on the ocean floor, the pale, ghostly appearance of a unique octopus species inspired diverse reactions.

"That animal is not in the ... guide," said a researcher from the聽NOAA Office of Ocean Exploration and Research. "In the immortal words of Taylor Swift, I have never 鈥� like ever 鈥� seen that one."

They , believed to be a new species of octopus,聽sitting on flat rock聽4,000 meters (13,123 feet) below sea level near Hawaii,聽Michael Vecchione,聽a National Oceanic and Atmospheric Administration (NOAA) zoologist, wrote in a statement.

"This animal was particularly unusual because it lacked the pigment cells, called chromatophores, typical of most cephalopods, and it did not seem very muscular,"聽Mr. Vecchione wrote. "This resulted in a ghostlike appearance, leading to a comment on social media that it should be called Casper, like the friendly cartoon ghost."

Vecchione " while monitoring the video feed from the remotely operated vehicle Deep Discover, which launched from the NOAA's only federally funded vehicle for deep-sea research, the ship聽Okeanos Explorer, Christine Dell'Amore聽reported for National Geographic.聽

"I knew it didn鈥檛 look like anything that鈥檚 been documented聽in the聽scientific聽literature,"聽Vecchione told National Geographic.

The octopod's suckers were arranged in one, rather than two series along its arms, and it had no fins, both characteristics generally reserved for shallow-water octopuses. Its pale appearance and lack of muscle, probably because so little food is available at those depths, are representative of its deep-water home. The creature did have eyes, however.

"When the sub got up close to it, it started climbing away, either reacting to lights of聽the聽sub聽or聽vibrations聽of聽the聽water," Vecchione told National Geographic.

Researchers suspect that the octopus represents a new species, and possibly a new genus as well, but it is not聽the first such discovery by the Okeanos Explorer, nor even the first octopus. At the end of a 2014 mission, the remotely operated Deep Discoverer on camera just as it was preparing to end its dive,聽Kasey Cantwell wrote in a NOAA blog post.聽

Most scientists who work with the Okeanos missions remain on-shore, but participate in research via live-feeds from ship, as did Vecchione. On its current mission, geologists have been keen to study the intact lava flows that formed the islands of Hawaii from their base, and of deep-sea coral, sponges, a聽dandelion siphonophore, and even a white tip shark, according to the ship's log.聽

This particular mission began Feb. 26 and concludes on March 18, and is the first deep-water dive in 2016. The crew aims to explore the Papah膩naumoku膩kea Marine National Monument to gather baseline research for conservation, deep-sea mining, and understanding of the聽potential US Extended Continental Shelf. The Okeanos Explorer's ongoing purpose is to by improving its knowledge of them.

"Resource managers cannot manage what they do not know," according to the NOAA.
