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. The giant Sunfish was almost at surface level and practically static. The Sunfish seemed not to be bothered by the presence of divers at all and followed them for 15 minutes.
