Graneledone boreopacifica is an octopus in the family Megaleledonidae. It can be found in both the Pacific and Atlantic Oceans.

The holotype of this species measures 9 cm in mantle length.[1]

The type specimen was collected in the Pacific Ocean (50°N, 151°E) and is deposited at the Zoological Institute in Saint Petersburg, Russia.[2]

A female Graneledone boreopacifica was observed in the Monterey Canyon by the Monterey Bay Aquarium Research Institute, brooding her eggs for a record 53 months, making this the longest brooding or pregnancy period known in the animal kingdom. This also makes it the longest living octopus – most octopuses only live for 1 or 2 years – which this octopus beats with its brooding period alone.[3][4]
