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.

Orangebäckchenastrild

A charming small estrildid finch with an unmistakable orange cheek patch set against a grey head, brown back, and pale white underparts, orange-cheeked waxbills are native to the humid forests and forest edges of West and Central Africa. They feed on small grass and weed seeds, often near water. Widely kept as aviary birds, they have established feral populations in parts of Puerto Rico, Europe, and Asia. Active and social, they pair bond strongly.
