There has been an extremely rare "megamouth" shark sighting near San Diego.
CBS 8 says fishermen spotted two megamouth sharks 30 miles from the coast.
Megamouth sharks have only been seen a few hundred times throughout history, and this could be the only known footage of two megamouths together.
The Scripps Institution of Oceanography says the megamouth sharks are so rare they don't know how many exist.
Most sightings are around southeast Asia and the warm ocean waters may be impacting the behavior of the marine life.
