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 strobilus is a marine haptophyte microalga in the family Prymnesiaceae. The specific epithet strobilus (Greek/Latin: pine cone or spinning top) likely references the conical arrangement of scales on the cell surface or the overall cell shape observed under microscopy. Like all members of the genus, C. strobilus is biflagellate and bears a haptonema, the defining appendage of the class Haptophyta. The organic scales covering the cell exterior are of species-specific morphology, serving as the primary character for species-level identification. C. strobilus inhabits marine photic-zone environments, with records from northern European and Scandinavian coastal waters. Chrysochromulina species collectively constitute a significant fraction of marine nanoplankton biomass and contribute to carbon fixation, dissolved organic matter production, and the microbial food web. Some congeners produce dimethylsulfoniopropionate and haemolytic toxins relevant to sulfur cycling and harmful algal events, respectively. The IUCN has not assessed the conservation status of C. strobilus, and it is classified as Not Evaluated. Its global distribution and population structure remain subjects of ongoing environmental survey and molecular studies.
