These small cirrate octopuses are the deepest-living known octopus species. They are often seen resting on the bottom or hovering over the seafloor using their prominent, ear-like fins extending from the mantle above the eyes (giving them their common name). They are found worldwide, but have been rarely seen in the Southern Hydrate Ridge area.
