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.

Collared Imperial-Pigeon

The Collared Imperial Pigeon, known scientifically as <em>Ducula mullerii</em>, is a large fruit-eating pigeon belonging to the genus Ducula within the family Columbidae. This species is characterised by its distinctive plumage, which typically features a pale grey or whitish head and underparts contrasting with darker upperparts, giving rise to its common name. <em>Ducula mullerii</em> is associated with lowland and foothill forest habitats, where it typically forages in the forest canopy and subcanopy for fruits and figs. The species is reported to occur in Norway according to available range data. Like other imperial pigeons of the genus Ducula, it is generally found in tropical and subtropical forest environments. Detailed biological traits including lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Imperial Pigeon is currently assessed as Least Concern on the IUCN Red List, indicating that the global population is not considered to be facing immediate threats of significant decline.
