When darkness falls... the Reef comes alive! 🦈 The #GreatBarrierReef is home to over 130 species of sharks and rays - these range from small docile Carpetsharks like seen here, to the top of the food chain in Tiger, Bull and Hammerhead sharks, all the way to the rarely encountered Whale shark. 🎥 Another incredible clip by @aleksmutated at @heronisland 👌 #SeetheReef #LovetheReef #ProtecttheReef #HeronIsland #SouthernGreatBarrierReef #Queensland #Australia #Shark
