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.

White-vented Plumeleteer

A medium-large hummingbird named for its white undertail coverts, white-vented plumeleteers have glittering green plumage with a brilliant pink-red bill and are found in humid lowland and foothill forest from Panama east through northern South America to Venezuela and Trinidad. They inhabit forest edges and clearings at elevations up to 1,400 meters. Males are aggressive territory defenders. Important pollinators of large-flowered Heliconias and other tropical understory plants across their range.
