blue whale

The largest animal ever known to have lived on Earth, blue whales can reach 33 meters and 200 tonnes — their hearts alone weigh as much as a small car. Found in all oceans, they migrate between polar feeding grounds and tropical breeding areas. Filter feeders consuming up to 4 tonnes of krill daily. Endangered, with global populations estimated at 10,000–25,000 after near-extinction from 20th-century whaling.

Red-crowned Crane

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.
