Taken while on honeymoon at Kuredu Island Resort in the Maldives. After many lovely comments we're getting closer to identifying the fish which are attacking the shoal. It seems they the aren't the blacktip reef sharks I once thought they were (update: they are Bluefin Travellys). Although they are featured in my other video (http://www.youtube.com/watc...).
As you can hear from the gasps, we weren't expecting this to happen! The squadron-like attack from the top is impressive and shows how they hunt in groups. Then the heron fails to catch a stunned fish. Well worth a replay - keep eyes at top of video!
