Description:
A new species of eledonid octopus is described from the southwestern Atlantic Ocean from depths between 90 and 1000 m off the coasts of southern Brazil, Uruguay, and Argentina. This species, Graneledone yamana is characterized by having a papillose skin, two well developed 'horns' above the eyes, small gills with 5-7 lamellae on the outer demibranch, arms with uniserial suckers, 35-80 on females and 26-70 on males. The third right arm is hectocotylized, the ligula is small, the calamus is large and well differentiated. Ink sac absent. These characters differ from all other known Graneledone species from the southern oceans.
