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.

Tawny-bellied Hermit

A large hermit hummingbird of humid Andean foothill forests in Peru, Ecuador, and Colombia, tawny-bellied hermits have warm tawny-buff underparts contrasting with greenish-bronze upper parts and a long, strongly curved bill. Found at elevations between 300–1,500 meters in montane forest understory. Like all large hermits, they are trap-line foragers visiting long routes of widely spaced flowers. Males assemble at traditional lek sites where they produce loud, repetitive vocalizations to attract females.
