Grand requin blanc

The largest predatory fish on Earth, great white sharks can reach 6 meters and 2,000 kg, inhabiting cool coastal and offshore waters in all major oceans. Apex predators employing ambush attacks from below, primarily on marine mammals, large fish, and seabirds. Despite their fearsome reputation, unprovoked attacks on humans are extremely rare. Vulnerable, with populations declining from finning, bycatch, and targeted fishing despite legal protections in many jurisdictions.

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.
