Swimming with Sperm Whales in Dominica

Off the west coast of Dominica, some two hundred sperm whales live year round in the deep water close to shore. On regulated swims, snorkelers slip into startlingly blue water as the great whales hang motionless below, their slow clicks carrying through the water. A tail fluke rising before a deep dive is the farewell image of the encounter. The whales are resident in every month, with the calmest seas from November through March.
