지구에서 살았던 것으로 알려진 가장 큰 동물로, 대왕고래(Balaenoptera musculus)는 33미터, 200톤에 달할 수 있으며, 심장만도 소형 자동차 무게와 비슷합니다. 모든 대양에 서식하며, 극지방 먹이 지역과 열대 번식 지역 사이를 이동합니다. 하루 최대 4톤의 크릴새우를 섭취하는 여과 섭식자입니다. 20세기 포경으로 인한 거의 멸종 이후 전 세계 개체수가 10,000~25,000마리로 추정되는 멸종위기 종입니다.

Chrysochromulina microcylindra is a species of marine haptophyte microalga in the genus Chrysochromulina, family Chrysochromulinaceae, class Prymnesiophyceae. The specific epithet microcylindra — small cylinder — refers to a minute cylindrical component of the scale structure on the cell surface, contrasting with the larger cylindrical scales of C. megacylindra and the shorter cylinders of C. brachycylindra. Together these three species illustrate the morphological continuum in scale cylinder dimensions within Chrysochromulina, and their differentiation highlights the role of quantitative ultrastructural measurements in haptophyte taxonomy. C. microcylindra has been recorded from Norwegian coastal marine environments and from Norwegian and Swedish waters more broadly, consistent with the established concentration of Chrysochromulina species diversity in Scandinavian coastal seas. These habitats are characterized by cold temperatures, high seasonal productivity driven by spring mixing of nutrient-rich deep water, and complex fjordic geomorphology that promotes diverse microhabitat niches for planktonic microalgae. The species is a nanoplankton organism engaged in photosynthesis using the typical prymnesiophyte pigment suite of chlorophylls a and c plus fucoxanthin. As with other genus members, mixotrophic capability is likely, allowing supplementary nutrition through phagocytosis of bacterial cells. C. microcylindra has not been evaluated under IUCN criteria and is listed as Not Evaluated. It represents one facet of the remarkable species richness that has emerged from systematic electron microscopy surveys of northern Atlantic nanoplankton.
