Lion d'Afrique

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical grasslands and savannas, and flooded grasslands and savannas, among 7 distinct biome types spanning the Afrotropic and Neotropic and Oceanian realms. Populations are also found in montane and highland environments at higher elevations.

Castor canadien

The largest rodent in North America, Canadian beavers weigh up to 32 kg and are master ecosystem engineers inhabiting rivers, lakes, and wetlands across Canada and the northern United States. By felling trees and constructing dams up to hundreds of meters long, beavers create ponds that provide habitat for hundreds of species. Their lodges and canals transform entire watersheds. Once nearly hunted to extinction for their fur, beaver populations have recovered strongly.

Lion d'Afrique

The largest wild cat in Africa, lions reach up to 250 kg and are the only social felids, living in prides across sub-Saharan savannas and grasslands. Males are distinguished by their iconic manes. As apex predators, they regulate herbivore populations and maintain ecosystem balance. Listed as Vulnerable due to habitat loss and human-wildlife conflict.
