Habitat & Geographic Range

Ecureuil gris

Habitat

Typically found in a wide range of habitat types.

Range

Widely distributed across Africa (South Africa), Asia (Indonesia), Europe (10 countries), and North America (Mexico, United States).

Guépard

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 9 distinct biome types spanning the Afrotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Botswana, Iran, Kenya, Namibia, and Tanzania. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Ecureuil gris

Native to eastern North America but successfully introduced to Europe and other regions, the eastern gray squirrel is a medium-sized arboreal rodent weighing up to 600 g. Highly adaptable, thriving in forests, parks, and urban gardens, gray squirrels cache thousands of nuts and seeds each autumn, inadvertently planting trees through forgotten caches. In Britain, they have largely displaced the native red squirrel by outcompeting them for food.

Guépard

The fastest land animal on Earth, reaching speeds of 112 km/h over short distances across African and Iranian grasslands. Slender build with a deep chest, long legs, and distinctive black tear-stripe markings. Unlike other big cats, cheetahs vocalize with chirps and purrs. Vulnerable, with only ~7,000 remaining due to habitat fragmentation and competition with larger predators.
