 There is a certain difference between these and the holotype in that the cirri start further up the arm in the South Georgia specimens, and it is possible that there are in fact two different species, one on each side of the Atlantic.More recently, evidence has been found of the presence of this species in the southern Indian Ocean.In a study, the stomach contents of a top predator in sub-antarctic waters, the Patagonian toothfish "(Dissostichus eleginoides)", were examined in order to see what octopuses and squid formed part of the diet.
