大翅鯨

座头鲸是大型鲸类中最具杂技表演性的物种之一，以繁殖季节雄性演唱的复杂而神秘的歌声著称，歌声有时持续数小时并随时间演变。体长可达16米，体重30吨，进行着哺乳动物中最长距离的洄游。分布于所有大洋，通过协作泡泡网捕食磷虾和小鱼。种群数量已从历史捕鲸后大体恢复。

Chrysochromulina pringsheimii is a haptophyte microalga in the family Prymnesiaceae, named for the German botanist Nathanael Pringsheim, who made foundational contributions to algal biology in the nineteenth century. The species follows the Chrysochromulina body plan: a biflagellate cell with a haptonema and a surface coat of organic scales arranged in overlapping layers. Scale morphology observed under electron microscopy provides the principal characters used to distinguish C. pringsheimii from related species. The species is found in marine and occasionally brackish coastal waters of northern Europe, consistent with the biogeographic concentration of described Chrysochromulina diversity in Scandinavian seas. As a nanoplankton primary producer, it participates in carbon fixation and the transfer of photosynthetically fixed carbon to higher trophic levels via grazing by heterotrophic nanoflagellates and microzooplankton. Some Chrysochromulina species produce dimethylsulfoniopropionate, contributing to the oceanic sulfur cycle. The conservation status of C. pringsheimii has not been evaluated by the IUCN, and the species is listed as Not Evaluated. Global environmental sequencing suggests that the diversity of haptophyte nanoflagellates in the world's oceans greatly exceeds what has been formally described.
