Northern fur seal

Able to spend long periods out in the open sea, some pups will stay up to 22 months before returning to land

The northern fur seals are the largest fur seal. Their fur color varies according to their age and gender. Females and young males generally have grey coats, while older males might be brownish-black, dark grey, or reddish-brown. Pups are black with buff-colored markings when they are born.

They are philopatry, meaning they will return to where they were born to give birth. Although females do not develop any social bond with other seals, they can recognize their offspring merely by their calls – even after being absent for several years.
