3-clawed crab caught on Oregon Coast

      SEASIDE, Ore. - If you like crab claws, maybe you should go crabbing with Nathan Fulton.

      Fulton caught a crab with three pinchers on Oct. 18.

      He donated the crab to the Seaside Aquarium so other people could take a look, too.

      So: What caused the crab to grow an extra claw?

      Tiffany Boothe at the Seaside Aquarium said crabs shed their shells as they grow new ones in a process called "molting."

      Sometimes a crab is injured while molting, which can cause strange deformities in the crab's shell, Boothe said.
