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.

Chrysochromulina mantoniae is a marine haptophyte alga named in honor of the pioneering British phycologist Irene Manton, whose electron microscopic studies of algal flagella and scales transformed the taxonomy of nanoplankton in the mid-twentieth century. The species belongs to the family Prymnesiaceae and displays the characteristic Chrysochromulina body plan: two heterodynamic flagella, a haptonema of variable length, and a cell surface coated with organic scales. C. mantoniae inhabits coastal marine waters of the North Atlantic, consistent with the geographic range of most formally described Chrysochromulina species. As a planktonic photosynthesizer and potential mixotroph, it contributes to the cycling of carbon and nutrients in the marine microbial food web. The haptonema's role in cell adhesion and prey capture has been studied extensively in closely related species, revealing complex behaviors including coiling and extension dynamics. The IUCN has not evaluated the conservation status of C. mantoniae, classifying it as Not Evaluated. This reflects the general absence of threat assessment methodology for free-living marine microorganisms whose populations are shaped largely by oceanographic rather than anthropogenic drivers.
