Split Dorsal Fin | Humpback Whale, Megaptera novaeangliae | Vava'u, Tonga

A male humpback whale with a split dorsal fin. This was one of eight whales engaged in an intense heat run at Toku Island. It was one of the most action-packed heat runs I've come across, with lots of grunting, snorting, lunging and other physical contact among the whales.
