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 laurentiana is a marine haptophyte microalga in the genus Chrysochromulina, class Prymnesiophyceae, order Prymnesiales. The species epithet laurentiana may reference the Gulf of St. Lawrence or Laurentian waters of the North Atlantic, suggesting a type locality or early collection site in the western North Atlantic, though it has also been recorded from Norwegian and Swedish coastal environments. This transatlantic pattern is consistent with oceanic dispersal of marine microplankton or with convergent description from morphologically identical but geographically distinct populations. C. laurentiana is a nanoplankton organism characterized by the standard Chrysochromulina features: golden-brown chloroplasts, two flagella, a coiling haptonema, and a cell surface bearing organic scales whose specific morphology is species-diagnostic. The species inhabits coastal marine photic zones, contributing to primary production and microbial food web dynamics. In northern Atlantic waters, Chrysochromulina species including C. laurentiana form part of the mixed phytoplankton community that drives seasonal productivity cycles, particularly in spring and early summer when nutrient availability and stratification favor nanoplankton growth. The genus as a whole is known for sporadic bloom-forming behavior in eutrophic or stratified coastal fjords, though such events are not universally associated with all species. C. laurentiana has not been formally assessed under IUCN Red List criteria and is classified as Not Evaluated, consistent with the standard treatment of widely distributed marine microalgal taxa.
