Common Bithynia

The common bithynia (<em>Bithynia tentaculata</em>) is a freshwater gastropod snail belonging to the family Bithyniidae. It is classified as Least Concern on the IUCN Red List and has been recorded across terrestrial and aquatic habitats in Belgium, Denmark, Norway, Sweden, and the United States. <em>Bithynia tentaculata</em> typically inhabits slow-moving or still freshwater environments such as lakes, ponds, canals, and rivers, often on muddy or sandy substrates where organic material is abundant. The species has a distinctive operculum that seals the shell opening, providing protection against desiccation and predators. It typically feeds by grazing on algae, detritus, and biofilms on submerged surfaces. The common bithynia serves as an intermediate host for several trematode parasites, making it ecologically significant in freshwater food webs and parasite life cycles. Biological traits of this species remain poorly documented in the scientific literature.

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.
