A 100-pound tropical fish was found on an Oregon beach, surprising scientists.

Photos from the nearby Seaside Aquarium show the huge opah, also known as a moonfish.

The aquarium said the fish, found on Sunset Beach in Seaside, was "rare to the Oregon Coast."

Tiffany Boothe, the aquarium's assistant manager, told The Washington Post that it was the first opah she had seen in beaches in the area.
