Habitat & Geographic Range

Buckelwal

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 (5 countries), and South America (Colombia, Ecuador, Venezuela). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Chrome-Footed Bolete

Habitat

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

Range

Distributed across Norway and United States.

Buckelwal

Among the most acrobatic of the great whales, humpback whales are renowned for their complex, haunting songs sung by males during breeding season — some lasting hours and evolving over time. Reaching 16 meters and 30 tonnes, they undertake the longest migrations of any mammal. Found in all oceans, humpbacks feed on krill and small fish using cooperative bubble-net feeding. Populations have largely recovered from historic whaling.

Chrome-Footed Bolete

The chrome-footed bolete (Xerocomus chrysenteron), sometimes treated as synonymous with Boletus chrysenteron, is a bolete mushroom in the family Boletaceae or Xerocomaceae, depending on the classification system applied. The genus Xerocomus has been subject to significant taxonomic revision in recent decades as molecular phylogenetic analyses have reshaped the boundaries of bolete genera. Species in Xerocomus are generally characterized by dry, often velvety caps, yellow to reddish stipes, and a tendency for cut flesh to stain blue. They form ectomycorrhizal relationships with deciduous and coniferous trees, contributing to the nutrient and water uptake capacity of their host trees. Xerocomus chrysenteron is found in temperate forests of Europe and has been recorded in similar forest types elsewhere, fruiting in summer and autumn. The cap often develops characteristic cracks revealing reddish flesh beneath an olive-brown surface. While edible, the species is considered inferior in quality to many other boletes, with soft flesh that deteriorates quickly. It is common and widespread with no conservation concerns of note. Taxonomic uncertainty surrounding the species complex has led to some confusion in identification, and multiple closely related species are now recognized within the broader Xerocomus group.
