Blauwal

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.

Rotschwanz-Schattenkolibri

A large hermit hummingbird of humid lowland and foothill forests from Central America through the Amazon basin, rufous-breasted hermits have cinnamon-rufous breast and underpart plumage contrasting with bronzy-green upper parts and a long curved bill. Males gather at leks — communal singing assemblies — where they perform vocal displays to attract females. They follow trap-line routes through dense forest understory. Important pollinators of large Heliconia flowers in tropical rainforest.
