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.

Alouette hausse-col

The most widely distributed lark species, common horned larks — also called shore larks in Europe — inhabit bare, open ground from Arctic tundra and alpine fellfield to coastal beaches and prairie across North America, Europe, Asia, and North Africa. Named for the small black feather tufts on the male's head. They are among the first birds to arrive at breeding grounds in early spring while snow still covers the tundra. They forage on seeds and insects on the ground year-round.
