Like most octopuses, they have a rounded body, eight limbs (arms) and no fins. However, unlike most octopuses, argonauts live close to the surface rather than on the seabed. Argonauta species are characterised by very large eyes and small webs between the arms. The funnel–mantle locking apparatus is a major diagnostic feature of this taxon.
Like other cirrate octopods, G. challengeri has fins on either side of its mantle that it uses to swim through the ocean. This octopus's fins are long. It also has a beak, as do other octopuses. [5] G. challengeri is a red-brown color when preserved, and its fins have a slight purple hue. [5] The octopus's lifespan is unknown.
