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.

Mute Swan

The most commonly encountered swan globally and one of the largest flying birds, mute swans weigh up to 15 kg and inhabit lakes, rivers, and coastal bays across Europe and Asia, with widespread introduced populations in North America and Australia. Despite their name, mute swans produce a range of hissing, grunting, and wing-whistling sounds. Males aggressively defend territories and are capable of injuring humans and drowning dogs with powerful wing strikes.
