Amphioctopus marginatus is a species of octopus located in the family Octopodidae, genus Amphioctopus. The species was first described in 1964 by Japanese malacologist Iwao Taki as Octopus marginatus, and synonymously as Amphioctopus marginatus. In 1976, Z. Dong named the species Octopus striolatus but this name was not recognized as ...
The genus Amphioctopus was subsequently considered invalid. In 2002, Gleadall suggested that the aegina species group represents a distinct genus with Amphioctopus being the senior name. In 2004, Gleadall resurrected the genus Schizoctopus and assigned Octopus fangsiao as the type species. [4]
The octopus Amphioctopus marginatus. Two groups of invertebrates have notably complex brains: arthropods (insects, crustaceans, arachnids, and others) and modern cephalopods (octopuses, squid, cuttlefish) and other molluscs. [14] The brains of arthropods and cephalopods arise from twin parallel nerve cords that extend through the body of the ...
At least four individuals of the veined octopus (Amphioctopus marginatus) have been observed retrieving discarded coconut shells, manipulating them, transporting them some distance, and then reassembling them for use as shelter. [36]
In 2005, Adopus aculeatus and veined octopus (Amphioctopus marginatus) were found to walk on two arms, while at the same time mimicking plant matter. [96] This form of locomotion allows these octopuses to move quickly away from a potential predator without being recognised. [94]
