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 alifera is a unicellular haptophyte microalga belonging to the class Prymnesiophyceae, order Prymnesiales, family Chrysochromulinaceae. Like all members of the genus Chrysochromulina, it is characterized by the presence of a coiling haptonema, a unique organelle distinct from flagella that assists in prey capture and surface attachment. C. alifera is a nanoplankton organism, typically ranging from a few micrometers in diameter, and forms part of the phytoplankton communities in marine and occasionally brackish coastal waters. The species was documented from Norwegian and Swedish coastal waters, habitats typical for many Chrysochromulina taxa that were first described by Scandinavian phycologists during the mid-twentieth century surveys of northern European marine microflora. These waters provide cold, nutrient-rich conditions suitable for haptophyte proliferation. C. alifera, like its congeners, likely plays a role in marine carbon cycling and is capable of mixotrophic nutrition, supplementing photosynthesis by ingesting bacteria and small organic particles. The species has not been formally evaluated under IUCN criteria, as microalgal taxa at this taxonomic level are rarely assessed due to difficulties in delimiting populations and determining extinction risk in planktonic organisms. Current conservation status is listed as Not Evaluated. Its ecological significance lies within the broader context of marine microbial food webs, where haptophytes serve as primary producers and food sources for zooplankton and protozoans.
