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 rotalis is a marine haptophyte alga in the family Prymnesiaceae. Its specific epithet may reference the circular or rotating arrangement of scales observed on the cell surface. Like all Chrysochromulina species, cells are biflagellate and equipped with a haptonema — the coiling, three-membrane appendage unique to haptophytes. Organic scales of species-specific morphology cover the outer cell surface, constituting the primary taxonomic diagnostic feature for species identification within this morphologically similar genus. C. rotalis inhabits the photic zone of coastal marine and shelf waters, particularly in temperate and subarctic seas. The genus as a whole is a dominant component of the haptophyte nanoplankton community in North Atlantic and Arctic waters. Some congeners are capable of sustained bloom formation under conditions of thermal stratification and elevated nutrient availability. Chrysochromulina blooms have ecological consequences for marine food webs and, in the case of toxic species, for fisheries and aquaculture. The IUCN has not assessed the conservation status of C. rotalis, and the species remains Not Evaluated. Its ecology, physiology, and population genetics across oceanic regions are incompletely documented.
