Habitat & Geographic Range

Cheetah

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.

Cheetah

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.

Haladaptatus pallidirubidus is a halophilic archaeon in the family Halobacteriaceae producing pale reddish-pink colonies due to carotenoid pigments. Like other members of its genus, it is adapted to moderate-to-high salinity environments and was isolated from saline water sources. Its carotenoids likely provide photoprotection and may contribute to photoactive metabolic pathways.
