Habitat & Geographic Range

Ballena azul

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

Common Bird'S Nest

Habitat

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

Range

Widely distributed across Asia (Taiwan), Europe (Norway, Portugal, Sweden), North America (United States), and South America (Brazil).

Ballena azul

El animal más grande que se conoce haya vivido en la Tierra; las ballenas azules pueden alcanzar 33 metros y 200 toneladas — sus corazones solos pesan tanto como un automóvil pequeño. Se encuentran en todos los océanos y migran entre las zonas de alimentación polares y las áreas de reproducción tropicales. Son filtradoras que consumen hasta 4 toneladas de kril al día. En peligro de extinción, con poblaciones globales estimadas entre 10.000 y 25.000 tras casi extinguirse por la caza de ballenas en el siglo XX.

Common Bird'S Nest

The common bird's nest (<em>Crucibulum laeve</em>) is a small cup-shaped fungus belonging to the family Nidulariaceae, known for its distinctive nest-like fruiting bodies that contain egg-like spore packages called peridioles. It is classified as Least Concern on the IUCN Red List. The species has been documented in Taiwan, Norway, Portugal, Sweden, the United States, and Brazil, reflecting a wide global distribution. <em>Crucibulum laeve</em> typically grows on decaying wood, forest floors, and decomposing organic material, where it plays a role in breaking down cellulose-rich substrates. The funnel-shaped cups, often pale tan in color, are designed to use splashing raindrops as a dispersal mechanism, propelling the peridioles outward to deposit spores on new substrates. This splash-cup dispersal strategy is a distinctive adaptation shared among bird's nest fungi. Biological traits of this species remain poorly documented in the scientific literature.
