藍鯨

蓝鲸是地球上已知存在过的最大动物，体长可达33米，体重达200吨，其心脏单独就重达一辆小型轿车的重量。分布于各大洋，在极地觅食地和热带繁殖地之间进行迁徙。它们是滤食性动物，每日可消耗多达4吨磷虾。蓝鲸被列为濒危物种，20世纪捕鲸活动使其濒临灭绝，目前全球种群估计约为1万至2.5万头。

Chrysochromulina apheles is a marine haptophyte microalga in the genus Chrysochromulina, family Chrysochromulinaceae, class Prymnesiophyceae. Members of this genus are distinguished by their coiling haptonema, two flagella of approximately equal length, and a covering of organic scales on the cell surface — features used extensively in species identification through electron microscopy. C. apheles inhabits coastal marine environments and has been recorded from Norwegian and Swedish waters, regions where intensive phycological surveys during the late twentieth century yielded numerous new haptophyte species descriptions. These subarctic and temperate Atlantic coastal waters sustain diverse nanoplankton communities in which Chrysochromulina species are frequently abundant components. The epithet apheles derives from Greek, referencing a morphological characteristic of the cell or scale structure. As a phytoplankton organism, C. apheles participates in primary production, converting inorganic carbon to organic matter through photosynthesis, and may also engage in phagotrophy of bacterial cells. Some Chrysochromulina species produce polyunsaturated fatty acids and occasionally bioactive compounds. The taxon has not been evaluated under IUCN criteria and carries a conservation status of Not Evaluated, reflecting the general challenge of assessing extinction risk in free-living marine microalgae whose populations are cosmopolitan and difficult to census. Understanding the ecology and distribution of species like C. apheles contributes to knowledge of marine microbial diversity and the functioning of pelagic food webs in northern Atlantic ecosystems.
