No, it’s not a “Sea Monstah” as described by the Boston fishermen who recently went viral. It is monstrous in size, but they’re completely docile. This rare footage of a gigantic sunfish was captured on film by photographer Miguel Pereira off the coast of Portugal. The huge creature dwarfs the divers as it swims past. The slow-moving fish and clear water allow for some spectacular close-ups of this amazing animal.
