Chrysosphaerella longispina is a colonial chrysophyte alga in the genus Chrysosphaerella, notable for the long silica spines (longispina: Latin, long spine) that project from each cell in the colony. The genus is characterized by spherical or discoid colonies of photosynthetic cells that each secrete siliceous scales and elongated spine-like appendages, making Chrysosphaerella colonies distinctively bristled and visible under light microscopy. The long spines of C. longispina likely serve as anti-predation structures that make the colonies more difficult for zooplankton to ingest. C. longispina is found in cold, oligotrophic freshwater lakes, particularly in Scandinavia, where comprehensive chrysophyte surveys have documented its presence. Chrysosphaerella colonies contribute to freshwater primary production and the cycling of biogenic silica, which upon cell dissolution is deposited in lake sediments as microscopically identifiable remains. These silica structures are widely used by paleolimnologists to reconstruct past changes in lake water chemistry, thermal stratification, and climate. The conservation status of C. longispina has not been assessed by the IUCN; the species is listed as Not Evaluated.

Speckled Hummingbird

A medium-sized hummingbird with speckled or spotted underparts — unusual among hummingbirds dominated by plain or iridescent plumages — speckled hummingbirds inhabit cloud forest and forest edges in the Andes from Colombia and Venezuela south to Bolivia at elevations of 900–3,000 meters. The spotted underpart pattern provides remarkable camouflage when the bird perches on lichen-covered bark. They forage on nectar and small arthropods and are important pollinators of Andean epiphytes.
