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 ]
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]
