On the island of Tahiti, at a place called "At the end of the road", a jovial dance began in a beautiful late afternoon of October. A whale and his calf have taken up residence in the lagoon. But everyone knows that all childrens tend to play a little before falling asleep. Each year the humpback whales come to Polynesia for its warm waters to give birth and raise their calf before their big return in antartic. But will it still be possible to admire their dances in a few years?
