This little deep sea octopus is a new species - and may not even belong to any described genus.
The cute cephalopod was discovered by scientists aboard the NOAA ship Okeanos Explorer on a trip to explore the deep sea around Hawaii’s Necker Island with a remotely operated vehicle (ROV). It was found at a depth of 4,290m.
NOAA's Michael Vecchione says: "A distinctive characteristic was that the suckers were in one, rather than two, series on each arm. This animal was particularly unusual because it lacked the pigment cells, called chromatophores, typical of most cephalopods, and it did not seem very muscular, resulting in a ghostlike appearance, leading to a comment on social media that it should be called Casper, after the friendly cartoon ghost."
