Among the most acrobatic of the great whales, humpback whales are renowned for their complex, haunting songs sung by males during breeding season — some lasting hours and evolving over time. Reaching 16 meters and 30 tonnes, they undertake the longest migrations of any mammal. Found in all oceans, humpbacks feed on krill and small fish using cooperative bubble-net feeding. Populations have largely recovered from historic whaling.

Grue du Japon

One of the rarest cranes in the world, red-crowned cranes stand 1.5 meters tall and are revered in East Asian cultures as symbols of longevity, fidelity, and good fortune. They inhabit wetlands and marshes of Russia, China, Korea, and Japan, performing elaborate and graceful courtship dances involving synchronized leaps, bowing, and calls. Endangered, with the wild population estimated at just 2,750 individuals, threatened by wetland drainage and habitat loss.
