Ours brun

The world's most widely distributed bear species, brown bears range from North America and Europe across Russia to Japan, occupying forests, tundra, and alpine meadows. Adults can weigh up to 700 kg in coastal Alaskan populations. Omnivores that consume berries, roots, fish, and carrion, brown bears are a keystone species that distribute nutrients across landscapes. Most populations are stable, though some subspecies are threatened.

orque

The largest member of the dolphin family, orcas reach up to 9 meters and 6 tonnes and are found in every ocean from Arctic to Antarctic. Apex predators living in matrilineal pods with distinct dialects, hunting strategies, and cultural traditions that differ between populations. Some populations specialize in fish, others in marine mammals. No natural predators; orcas sit at the top of every marine food chain they inhabit.
