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.

Viridian Metaltail

A medium-sized hummingbird of the high Andes of Colombia and Ecuador, viridian metaltails inhabit open páramo grasslands and forest edges at 2,900–4,600 meters elevation. Males display distinctive green plumage with a glittering teal-green tail, while females are duller green below. Like all hummingbirds, they feed on nectar and small insects, hovering in stationary flight with wingbeats exceeding 50 per second. Listed as Least Concern with stable Andean populations.
