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。

Chroomonas vectensis is a species of cryptophyte alga in the family Chroomonadaceae, with the specific epithet vectensis suggesting a type locality or particularly strong association with the Isle of Wight (Vectis in Latin), off the southern coast of England. If correctly attributed, this would place the type collection in the coastal or brackish waters of the Isle of Wight or surrounding seas, suggesting this species may be adapted to marine or brackish conditions, as opposed to the strictly freshwater Chroomonas species. Marine cryptophytes are significant contributors to coastal phytoplankton and are important prey items in marine food webs. Chroomonas vectensis would share the general characteristics of the genus — small biflagellate unicells with a cryptophyte plastid bearing phycobiliproteins and chlorophyll a and c — while potentially possessing adaptations to saline or brackish conditions such as osmotic regulation mechanisms. Marine cryptophytes have received increasing scientific interest for their potential as sources of EPA (eicosapentaenoic acid), a valuable polyunsaturated fatty acid. Conservation status has not been assessed by the IUCN.
