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.

지구상에서 가장 키가 큰 동물인 기린(Giraffa camelopardalis)은 키가 5.5m에 달하고 체중이 최대 1,750kg에 이를 수 있다. 모든 포유류와 같이 7개의 경추로 이루어진 긴 목은 아프리카 사바나와 산림의 아카시아 나무 먹이 섭취를 위해 진화했다. 영구적인 결속 없이 느슨한 무리를 이루며 생활하는 사회적 동물로, 초저주파음과 몸짓으로 소통한다. 서식지 상실과 밀렵으로 개체군이 감소하고 있는 취약 종이다.
