Every year, 10% of the world's population of humpback whales migrates to Madagascar's waters.

From June to September the whales come from the Antarctic to reproduce in Madagascar's warmer waters. During this time they provide viewers with a magnificent mating display. By the end of August females give birth, and it is not unusual to see the mothers swimming with their calves.

Whales can be watched from Isle Sainte Marie, Tuléar, Fort Dauphin, Nosy Be and, of course, in the Antongil Bay, which latter location remains one of the world's best places to see these imposing yet graceful creatures.
