Common Least Skipper

The Common Least Skipper (<em>Ancyloxypha numitor</em>) is a small butterfly in the family Hesperiidae, classified as Least Concern on the IUCN Red List. It is native to Canada and the United States, where it typically inhabits virtually all terrestrial and freshwater habitats within its range, showing a particular affinity for moist, grassy areas near water. The species is among the smallest skippers in North America, characterized by orange and brown wing coloration and a rapid, low-flying flight pattern close to vegetation. Adults typically nectar on small flowers while larvae feed on grasses, particularly those in wet meadows, marshes, stream margins, and disturbed grassy areas. The Common Least Skipper is frequently observed in wetland margins, wet prairies, and roadsides with rank grass growth. Its wide distribution across North America and habitat generalism across moist grassland and wetland types support its stable population and Least Concern conservation status. Biological traits of this species remain poorly documented in the scientific literature.

European otter

유럽수달(Lutra lutra)은 유럽과 아시아 전역의 깨끗한 강, 개울, 해안선에 서식하는 날렵한 반수생 족제비과 동물입니다. 체장 최대 1.3미터에 달하며 민감한 수염으로 먹이의 움직임을 감지해 물고기를 사냥하는 뛰어난 능력을 가지고 있습니다. 풍부한 물고기가 있는 오염되지 않은 물이 필요하여 담수 생태계 건강의 지표종으로 알려져 있습니다. 한때 사냥과 오염으로 서유럽에서 거의 멸종 위기에 처했지만, 수질 개선 이후 개체수가 크게 회복되었습니다.
