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.

Gray-headed Lovebird

The only lovebird species native to Madagascar, gray-headed lovebirds — also called Madagascar lovebirds — are among the most sexually dimorphic lovebirds, with males having pale grey heads and necks contrasting with bright green body plumage, while females are entirely green. They inhabit forest edges, scrub, and cultivated areas of Madagascar and have been introduced to some neighboring islands. Relatively little kept in captivity compared to African lovebirds. Listed as Least Concern.
