Ocean sunfish or Mola mola are a rare find in the Puget Sound. These fish are generally found worldwide in temperate and tropical seas. They feed primarily on jellyfishes. Although the photo above is a small Ocean sunfish, they can get up to 2 meters in length and are known as the heaviest bony fish reaching over 2 tons.

I caught one, too about a week ago. I saw an adult one a couple years ago north of the Hartstine Island Bridge. It was HUGE!
