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.

Scaly-breasted Munia

One of the most widespread estrildid finches in Asia, scaly-breasted munias are named for the fish-scale-like pattern of brown and white streaks on their breast. They inhabit grasslands, rice fields, and scrub from India east through Southeast Asia to the Philippines and Indonesia, and have established feral populations in many parts of the world including Hawaii, Florida, and Australia. Highly gregarious, they form flocks of hundreds feeding on grass seeds and rice grains.
