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.

Gorille de l'Ouest

The world's largest primate, western gorillas weigh up to 180 kg and inhabit the tropical and subtropical forests of equatorial Africa. Primarily herbivorous, living in family groups led by a silverback male who protects the troop and mediates social conflicts. Critically Endangered, with populations threatened by deforestation, poaching for bushmeat, and outbreaks of Ebola virus disease.
