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 pyramidosa is a unicellular marine haptophyte microalga in the genus Chrysochromulina, family Chrysochromulinaceae, class Prymnesiophyceae. The species epithet pyramidosa, meaning pyramid-shaped, refers to a pyramidal morphological feature — most likely a scale element or a distinctive cell shape — visible under electron microscopy. Within Chrysochromulina, the three-dimensional geometry of scales is a primary taxonomic character, and pyramid-shaped scales represent one of several distinctive scale forms distributed across the genus. C. pyramidosa has been documented from Norwegian and Swedish coastal marine environments, part of the extensive Scandinavian haptophyte biodiversity documented through systematic surveys of northern Atlantic coastal waters. These environments are characterized by cold, highly productive waters influenced by the North Atlantic Current and seasonal upwelling of nutrient-rich deep water. Chrysochromulina species including C. pyramidosa are common nanoplankton constituents in these systems, particularly during stratified summer conditions when nutrient depletion in surface waters selects for smaller, more efficient phytoplankton cells. Like other genus members, the species is presumed to employ both photosynthesis and potentially phagotrophic nutrition to sustain itself in variable nutritional environments. C. pyramidosa carries a conservation status of Not Evaluated under IUCN criteria. It represents one of the geometrically diverse scale forms documented within Chrysochromulina, contributing to the broader picture of haptophyte morphological evolution and diversity in temperate Atlantic marine systems.
