Fishermen spotted two extremely rare megamouth sharks off the coast of San Diego. The sharks have only been seen a few hundred times throughout history. "We didn't really process the rarity of the situation until later on," said Val Costescu. Costescu, David Stabile, and Andrew Chang were about 30 miles off the coast fishing when they captured a video of the sharks swimming under their boat on Sunday. Chang recognized the rare species right away. "Right when we got close he threw out oh my gosh I think that's a mega mouth," Stabile said. The group took their footage to Scripps Institution of Oceanography to confirm what they saw. "I think with each person we were put in contact with, the gravity of everything started to sink in with us that we truly had an out of this world unique experience," Stabile said.
