![]() It is what gives the octopus its round bell shape. This means that they have webs of skin connecting their tentacles. Belonging to the Opisthoteuthidae family, they are a type of umbrella octopus. The duo named the species Grimpteuthis imperator, and Emperor Dumbo or Kaiser Dumbo as a proposed common name because the specimen was discovered along the slopes of the Emperor seamount chain in the Pacific Ocean.

However, before disappearing into the friendly skies, I alerted the other expedition participants to the possibility that this was. Aptly named after the lovable flying elephant, Dumbo, from the Disney cartoon classic because of the little flaps that stick out of their mantle that look just like Dumbo’s ears. The largest Dumbo octopus ever recorded was 5 feet 10 inches (1.8 m) long and weighed 13 pounds (5.9 kg), but most species are an average size of 7.9 to 12 inches (20-30 cm) long. The Dumbo Octopus, Grimpoteuthis, is a group of octopuses that include 14 individual species, who are all as endearing as the next. It lives at least 13,100 feet (4,000 m) below the surface. "That moment when we realized we were describing a new species, obviously, that was a pretty good moment." Further complicating the identification, I knew that another squid in a related family (Narrowteuthis nessisi, in family Neoteuthidae) is very similar and easily confused with a small giant squid (yes, an oxymoron). The Dumbo octopus is the deepest-living genus of all known octopuses. "Christina was calculating these values and counting the suckers when we realized it didn't compare to other species," Ziegler said. ![]() For one, the number of suckers on its tentacles, along with the shape of the gills and beak, suggested something totally new. Instead, Ziegler and his master's student at the time, Christina Sagorny, currently a doctoral student in Ziegler’s lab, used magnetic resonance imaging (MRI) and micro-computed tomography (micro-CT) scans to noninvasively examine the internal organs and structure of the octopus without making a single cut except to extract a DNA sample.īy using these techniques, Sagorny and Ziegler found that their endearing deep-sea dweller didn't match any known species. "You have to look at the internal structure, which would mean disassembling the specimen in order to describe it," Ziegler said. The average depth of most dumbo octopus species is 13,100 feet (4,000 m), though some have been found as deep 23,000 feet (7,000 m) Because of this very deep niche, dumbo octopuses have some very interesting adaptations. To identify an octopus to the species level, or to characterize it as a new species typically requires destructive techniques. The Dumbo Octopus is the common name for a genus of octopuses that live in the deepest parts of the ocean.
