African elephant

아프리카코끼리(Loxodonta africana)는 지구상에서 가장 큰 육상 동물로, 최대 7,000 kg에 달하며 사하라 이남 아프리카의 사바나, 삼림, 습지에 서식한다. 뛰어난 지능을 가지며, 모계를 중심으로 한 복잡한 사회 구조를 이루고 초저주파음, 울음소리, 촉각을 통해 의사소통한다. 나무를 쓰러뜨리고 물웅덩이를 파며 씨앗을 산포하는 생태계 엔지니어로, 현재 취약(VU) 종으로 분류되며 상아 밀렵과 서식지 손실로 인해 개체수가 감소하고 있다.

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.
