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.

Chrysolykos angulatus is a unicellular freshwater chrysophyte microalga in the genus Chrysolykos, class Chrysophyceae. The genus Chrysolykos is a small and specialized group within the golden algae, distinguished by its unique lorica structure — a rigid outer envelope enclosing the cell that bears distinctive angular or geometric features. The species epithet angulatus — angled or angular — directly references the characteristic angular profile of this species' lorica, distinguishing it from related species with more rounded forms. C. angulatus has been documented from Norwegian freshwater environments, consistent with the concentration of Chrysolykos species records in Scandinavian limnological surveys. These cold, typically nutrient-poor freshwater systems provide favorable conditions for chrysophyte diversity. The species inhabits the photic zone of freshwater lakes and ponds, where it contributes to primary production as a photoautotroph. Like other chrysophytes, C. angulatus possesses chloroplasts with chlorophylls a and c and fucoxanthin-type carotenoids, producing the golden-brown coloration typical of the group. Chrysolykos cells are small nanoplankton organisms whose exact ecological role in freshwater food webs is not well studied, though they likely participate in bacterial grazing and serve as food for small zooplankton. The genus is rarely encountered in high abundance and is considered a minor component of most phytoplankton communities. C. angulatus has not been evaluated under IUCN criteria and is listed as Not Evaluated, reflecting the general status of freshwater microalgal taxa for which detailed population data are unavailable.

giraffe

The tallest living animal on Earth, giraffes can reach 5.5 meters in height and weigh up to 1,750 kg. Their elongated necks — containing the same seven cervical vertebrae as all mammals — evolved for feeding on acacia trees in African savannas and woodlands. Social animals living in loose herds with no permanent bonds, giraffes communicate through infrasound and body language. Vulnerable, with populations declining due to habitat loss and poaching.
