Amphioctopus is a genus of octopuses comprising around 16 species.
Description
Members of the genus Amphioctopus reside in tropical and subtropical waters. These octopuses are found primarily in the Pacific and Indian Oceans but representatives can also be found in the Atlantic. They are characterized by arms that are about two or three times their mantle length with deep lateral webs and very shallow dorsal webs.[1] This genus can be further divided into two subgroups, one group with ocellate octopuses, the other with non-ocellate octopuses.[2]

Several members of Amphioctopus may represent species complexes that require additional attention or detailed redescription, in particular: A. fangsiao (Gleadall, 2004), A. granulatus, and A. marginatus. Many members of this group are undescribed or poorly described despite their high fisheries potential in some tropical regions of the world.
