The tail-slap – Humpback Whale

BLACK AND WHITE

Tail-slapping is an energetic behaviour, particularly when whales are fasting on their southern migration back to their Antarctic feeding grounds. Whether it is to show off or just to dust off a few parasites, it is an awesome and noisy spectacle. Since 2006, I have photographed 1480 whales in Exmouth Gulf for a scientific catalogue.
