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.

Glossy Flowerpiercer

A medium-sized flowerpiercer with glossy, iridescent blue-black plumage that catches light with a deep metallic sheen, glossy flowerpiercers use their specialized hooked bill to pierce flower bases and rob nectar without effecting pollination — a form of nectar theft that has evolved independently multiple times in birds. Found in humid Andean cloud forest and forest edges from Colombia to Bolivia at elevations of 1,500–3,500 meters. Common in forest edges and gardens with abundant tubular-flowered plants.
