The Ocean's fastest Swordsman: Sailfish Hunting The Sailfish is widely considered the fastest fish in the ocean, capable of short bursts up to 68 mph. When hunting schooling fish, they raise their massive dorsal sail to corral the prey, making themselves look larger. They then use their rough, bill-like snout to slash through the school, stunning or injuring individual fish before circling back to eat them. This footage captures the chaotic energy of a baitball attack. #nature #naturelover #anim
