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.

gorilla

세계에서 가장 큰 영장류인 서부고릴라는 체중이 최대 180kg에 달하며 적도 아프리카의 열대 및 아열대 삼림에 서식한다. 주로 초식성이며, 무리를 보호하고 사회적 갈등을 중재하는 실버백 수컷이 이끄는 가족 집단을 이루어 생활한다. 삼림 벌채, 식육용 밀렵, 에볼라 바이러스 발병의 위협으로 인해 심각한 위기(CR) 종으로 지정되었다.
