흰머리독수리(Haliaeetus leucocephalus)는 미국의 국조이자 미국 자연 보전 성공의 상징으로, 날개 폭이 최대 2.4미터에 달하며 북미 전역의 수변 삼림과 습지에 서식한다. 주로 물고기를 포식하는 강력한 공중 포식자이자 청소 동물로, DDT 오염과 남획으로 1960년대에 멸종 위기에 처했으나 농약 사용 금지와 멸종위기종보호법 시행 이후 극적으로 개체수가 회복되었다.

common river snail

<em>Viviparus viviparus</em>, the common river snail, is a freshwater gastropod mollusk in the family Viviparidae, order Architaenioglossa. It is distributed across Europe, with populations documented in Austria, Belgium, Bulgaria, Czech Republic, France, Germany, and Hungary, among other countries, typically inhabiting slow-moving and still freshwater bodies including rivers, canals, ponds, and ditches. The species is assessed as Least Concern on the IUCN Red List. Common river snails typically live in soft-sediment benthic habitats, grazing on algae, aquatic plant material, and organic detritus using a radula — a ribbon-like feeding organ characteristic of gastropods. <em>Viviparus viviparus</em> is notable among freshwater mollusks for being viviparous, giving birth to fully formed juvenile snails rather than laying eggs, an adaptation reflected in both the genus and family names. This reproductive strategy typically results in small litter sizes but high juvenile survival compared to egg-laying mollusks. The species plays a role in benthic nutrient cycling and serves as prey for waterfowl, fish, and crayfish. Biological traits such as precise lifespan, body measurements, and population density data vary across localities and remain incompletely documented in comprehensive studies.
