Shakotan Peninsula- LIFE BELOW WATER

01m 24s

The sea off Hokkaido’s Shakotan Peninsula is a winter breeding ground and attracts various creatures, including this 3-meter-long mizudako, or giant Pacific octopus. They’re the world's largest octopus and come from the deep sea to mate in shallower waters. This one gets warned off when he enters the territory of a male hokke, or Atka mackerel, whose job is to protect eggs scattered across the rocks.
