In summer during their breeding season humpback whales come closer to the water surface and amuse visitors with their stunts. They swim along the coast springing out of water and slapping it with their tails. One may also hear whales singing their marine songs. Madagascar offers to experience such spectacular performances near its eastern coasts in the Saint Marie Channel. Every year these large mammals migrate here from the South Pole for their breeding season since this area is protected by the east coast of Madagascar and Saint Marie Island. The whales remain here for the next four months, the time necessary for the newborn calves to grow up. In September enlarged whale families return back to the South Pole.
