Alan J. Jamieson, scientist at the University of Newcastle, Has published in Marine Biology who has managed to overcome the identification of an octopus at a depth of 1,800 meters.
Specifically, two direct observations of the cirrate octopod Grimpoteuthis sp., commonly known as Dumbo octopus, at 5760 and 6957 meters in the Java Trench (Indian Ocean).
Dumbo Octopus
In April 2019, three autonomous bait cameras and identical traps with conductivity, temperature and depth sensors were deployed during the Indian Ocean stretch of the Five Deeps Expedition (2018-2019).
Cephalopods are not generally considered characteristic of the benthic fauna at hadal depths (depths greater than 6 000 metres). In this study, unequivocal sightings are reported, therefore, increasing the potential benthic habitat available for cephalopods from 75 to 99% of the global seafloor.
Sometimes called "Dumbo octopuses" because of their ear-like fins that project over their "heads" (bodies), resembling the flying ears of Walt Disney's elephant. The largest specimens reach 20 cm, but little is known about their habits.. The "Dumbo octopus" has 8 tentacles with 60 to 70 suckers on each one. Their distribution pattern distinguishes whether they are male or female. There are 13 species discovered so far. Each of these is of different colors (red, white, brown, pink), sizes and shapes.
