Northern Sea Otter (Enhydra lutris kenyoni)

This photo was taken in 2013.

The individual is a Male named "Yutan". It was born at Notojima Aquarium in 2000, and transfered to Hakkeijima, where it deceased in 2017.

Hakkeijima no longer holds Sea Otters.

@Toki Those were the days when many major aquariums had sea otters. Now only two holders

@Dr. Wolverine
Yes, I remember meeting otters at many aquariums back then. Too sad the breeding programs didn't go well.
