Description: This one is a Muusoctopus (the new name for Benthoctopus). It is not Muusoctopus januarii and certainly not Pteroctopus tetracirrhus. It might be a Muusoctopus johnsonianus but they are usually paler that this with more distinct reverse countershading. I suspect that there are undescribed species in the Gulf of Mexico and this may be one.
Octopus with 2 rows of suckers on each arm and 8 arms. This narrows it down a bit. It is a female as no reproductive arm (hectocotylus) is visible on the third right arm. An old reference on the recorded deep-water octopus from the GoM (Voss, 1956) seems out of date compared to modern knowledge.
