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.

Great White Pelican

One of the world's largest pelicans, great white pelicans have wingspans reaching 3.6 meters and inhabit shallow lakes and wetlands across Europe, Africa, and Asia. Social birds breeding in large colonies and foraging cooperatively — groups of pelicans corral fish into shallow water before scooping them in their expandable throat pouches. Their pouches can hold up to 13 liters of water. Listed as Least Concern globally with stable populations.
