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 brachycylindra is a species of unicellular haptophyte microalga in the genus Chrysochromulina, class Prymnesiophyceae. The specific epithet brachycylindra refers to a morphological feature — likely a short cylindrical element of the cell's scale or haptonema structure — distinguishing it from related species. Chrysochromulina species are marine nanoplankton organisms covered in species-specific organic or mineralized scales, which together with haptonema length, flagella structure, and cell dimensions provide the principal characters for species delimitation. C. brachycylindra has been recorded from Norwegian coastal marine environments, part of the extensive northern European haptophyte fauna documented through electron microscopy surveys. Norwegian fjords and coastal shelf waters offer cold, seasonally productive conditions that support diverse haptophyte assemblages, with Chrysochromulina species often dominating nanoplankton communities during spring and summer stratification. The species is presumed to be photoautotrophic or mixotrophic, acquiring carbon both through photosynthesis using chlorophylls a and c and fucoxanthin-like accessory pigments, and potentially through ingestion of bacteria or small organic particles. Notable Chrysochromulina blooms in Norwegian waters have historically caused damage to fish farms, though C. brachycylindra specifically has not been implicated in harmful bloom events. The species carries a conservation status of Not Evaluated under IUCN criteria, as microalgal plankton taxa in this size class are not routinely assessed for extinction risk given their broad dispersal potential and microscopic nature.
