In the Neckar Island area near Hawaii, the team from NOAA Ship Okeanos Explorer Found a really cute little octopus at a depth of about 4200 meters. So far the animal was completely unknown and was seen and described for the first time and you can hear the enthusiasm of the scientists in the video.
Deep-sea octopods are easily separated into two distinct groups: (1) the cirrate, or finned, octopods (also known as “dumbo” octopods), characterized by fins on the sides of their bodies and fingerlike cirri associated with the suckers on their arms and (2) incirrate octopods, which lack both fins and cirri and are similar in appearance to common shallow-water Octopus. The octopod imaged in detail on this first dive was a member of the second group, the incirrates. 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. This resulted in a ghostlike appearance, leading to a comment on social media that it should be called Casper, like the friendly cartoon ghost. It is almost certainly an undescribed species and may not belong to any described genus.
Regardless of the ghostly and yet somehow cute appearance, it was quickly agreed that his name should be Casper, like the friendly ghost. Once you've determined it, it gets a scientific name - but Casper is very, very apt ...
