Habitat & Geographic Range

Cobalt Crust

Habitat

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

Range

Distributed across Chile, Norway, and United States.

Epaulard

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 11 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Taiwan), Europe (4 countries), and South America (Colombia, Ecuador, Venezuela).

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.

Epaulard

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.
