Habitat & Geographic Range

Cobalt Crust

Habitat

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

Range

Distributed across Chile, Norway, and United States.

Jirafa

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and flooded grasslands and savannas, among 5 distinct biome types within the Neotropic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Found in Ecuador. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

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.

Jirafa

La jirafa (Giraffa camelopardalis) es el animal terrestre más alto de la Tierra, puede alcanzar 5,5 metros de altura y pesar hasta 1.750 kg. Su elongado cuello, que contiene las mismas siete vértebras cervicales que todos los mamíferos, evolucionó para alimentarse de acacias en sabanas y bosques africanos. Animal social que vive en manadas sueltas, se comunica mediante infrasonidos y lenguaje corporal. Clasificada como Vulnerable debido a la pérdida de hábitat y la caza furtiva.
