baleine bleue

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.

Colibri de Mulsant

A tiny woodstar hummingbird inhabiting the Andes and inter-Andean valleys from Colombia to Bolivia, white-bellied woodstars are among the smallest hummingbirds with males weighing just 2.5 g. Males display a vivid amethyst-purple gorget and white belly with green flanks. Found at forest edges and gardens from 1,500–3,500 meters elevation. Despite their diminutive size, they are aggressive and highly maneuverable, entering torpor at night to conserve energy in cold Andean conditions.
