Chrysosphaerella brevispina is a colonial chrysophyte alga in the genus Chrysosphaerella, class Chrysophyceae. The genus is defined by its colonial organization: cells are arranged in spherical or discoid colonies in which each cell bears siliceous scales on its surface and projects stiff, spine-like silica bristles outward. The specific epithet brevispina (Latin: short spine) describes the relatively short silica spines that distinguish this species from congeners bearing longer projections. C. brevispina is found in freshwater environments, particularly in oligotrophic lakes and ponds of Scandinavia, where chrysophyte communities are richest. Chrysosphaerella species, like other chrysophytes, thrive in cold, clear, soft-water habitats and are sensitive indicators of water quality. The silica spines and scales produced by Chrysosphaerella cells are preserved in lake sediments as microfossils, providing paleoenvironmental records stretching back thousands of years. The spines may function as anti-grazing structures, reducing ingestion by zooplankton. The species has not been evaluated for conservation status by the IUCN and is listed as Not Evaluated. Its ecology and distribution in lakes outside Scandinavia are incompletely documented.

Common Sword-nosed Bat

<em>Lonchorhina aurita</em>, the common sword-nosed bat, is a microchiropteran bat in the family Phyllostomidae, order Chiroptera. It is distributed across northern South America, with confirmed records from Colombia, Ecuador, and Venezuela, typically roosting in caves, tunnels, and hollow trees in humid tropical forests. The species is named for its exceptionally elongated, sword-like noseleaf, one of the most prominent of any bat species, which is thought to play a role in echolocation signal emission and directionality. <em>Lonchorhina aurita</em> is insectivorous, feeding primarily on insects captured in flight through echolocation within forested environments. It is typically gregarious, roosting in colonies that may include hundreds of individuals. Biological traits including average lifespan, body mass, and forearm length under field conditions remain poorly documented in the scientific literature. The species is assessed as Least Concern by the IUCN, with a reasonably broad distribution and populations that are not currently under severe threat, though continued deforestation and cave disturbance in South America may pose growing risks to local colonies over the long term.
