PRINCE OF WHALES
The Kaikoura coast is host to a number of species of whales and dolphins, including migrating Humpback Whales, Pilot Whales, Blue Whales and Southern Right Whales. But the undisputed prince among them is the giant Sperm Whale. The Sperm Whale is the largest of all toothed whales and is believed to be the largest toothed animal to ever inhabit Earth, measuring up to 18m long.
