Core Insights - A new deep-sea octopus species named "Flying Ash Octopus" has been discovered by the Institute of Oceanology, Chinese Academy of Sciences, highlighting the biodiversity in deep-sea environments [1][4] - The research provides evidence supporting the taxonomic classification of the Ash Octopus genus and suggests a revision in the classification of recent octopuses [3][4] Group 1: Discovery and Classification - The Flying Ash Octopus was found at a depth of 1240 meters in the Caroline Seamount of the western Pacific, measuring approximately 20 centimeters in length and exhibiting a translucent orange-red color [1] - The study confirmed the monophyly of the Ash Octopus genus and provided new evidence for the classification of the suborder with two distinct superfamilies [3] Group 2: Adaptation Mechanisms - The research explored the deep-sea adaptation strategies of octopuses, indicating that they may reduce active swimming and lower movement speed to decrease metabolic demands, allowing mitochondrial respiration to function normally [4] - These adaptations enable the octopus to thrive in extreme deep-sea conditions characterized by high pressure, low temperature, and low oxygen [4]
