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.

Cobalt Crust

Habitat

Typically found in forest floors, decomposing wood, and soil ecosystems.

Range

Distributed across Chile, Norway, and United States.

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.

Cobalt Crust

Cobalt crust (Terana coerulea) is a distinctive crust-forming basidiomycete fungus in the family Phlebiaceae (order Polyporales), found across a broad range spanning Europe, North America, parts of Asia, and Australasia. It grows on the underside of dead hardwood logs, branches, and fallen timber in humid woodland, forming brilliant cerulean to cobalt-blue, waxy, resupinate fruiting bodies that are among the most visually striking of all wood-decay fungi. The vivid blue coloration results from the production of a pigment called corulein or is associated with the interaction of copper with fungal metabolites. Despite its startling appearance, cobalt crust is a typical white-rot fungus that decomposes cellulose and lignin in dead wood, contributing to nutrient cycling and soil formation in forest ecosystems. It is best detected during wet autumn and winter months when fruiting is most prolific. Its IUCN conservation status is Not Evaluated, consistent with its wide distribution and occurrence in many protected woodland areas. Cobalt crust is a sought-after find by mycologists and nature photographers due to its extraordinary coloration.
