common freshwater nerite

<em>Theodoxus fluviatilis</em>, commonly known as the common freshwater nerite, is a small aquatic gastropod mollusc belonging to the family Neritidae. This species is widely distributed across Europe, with documented occurrences in Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Hungary, Latvia, Norway, and Sweden. It typically inhabits freshwater environments, including rivers, streams, and lakes, where it grazes on algae and biofilm on hard substrates such as rocks and submerged wood. The common freshwater nerite is assessed as Least Concern on conservation metrics, reflecting its broad distribution and relatively stable populations across much of its European range. Biological traits of this species remain poorly documented in the scientific literature. <em>Theodoxus fluviatilis</em> plays an ecological role as a grazer in freshwater benthic communities, contributing to the regulation of algal growth on hard surfaces. The species typically favors clean, well-oxygenated waters and can serve as an indicator of water quality in freshwater systems. Its distinctive small, dome-shaped shell with variable patterning makes it recognizable among freshwater invertebrates.

Jirafa

La jirafa (Giraffa camelopardalis) es el animal terrestre más alto de la Tierra, puede alcanzar 5,5 metros de altura y pesar hasta 1.750 kg. Su elongado cuello, que contiene las mismas siete vértebras cervicales que todos los mamíferos, evolucionó para alimentarse de acacias en sabanas y bosques africanos. Animal social que vive en manadas sueltas, se comunica mediante infrasonidos y lenguaje corporal. Clasificada como Vulnerable debido a la pérdida de hábitat y la caza furtiva.
