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 alifera is a unicellular haptophyte microalga belonging to the class Prymnesiophyceae, order Prymnesiales, family Chrysochromulinaceae. Like all members of the genus Chrysochromulina, it is characterized by the presence of a coiling haptonema, a unique organelle distinct from flagella that assists in prey capture and surface attachment. C. alifera is a nanoplankton organism, typically ranging from a few micrometers in diameter, and forms part of the phytoplankton communities in marine and occasionally brackish coastal waters. The species was documented from Norwegian and Swedish coastal waters, habitats typical for many Chrysochromulina taxa that were first described by Scandinavian phycologists during the mid-twentieth century surveys of northern European marine microflora. These waters provide cold, nutrient-rich conditions suitable for haptophyte proliferation. C. alifera, like its congeners, likely plays a role in marine carbon cycling and is capable of mixotrophic nutrition, supplementing photosynthesis by ingesting bacteria and small organic particles. The species has not been formally evaluated under IUCN criteria, as microalgal taxa at this taxonomic level are rarely assessed due to difficulties in delimiting populations and determining extinction risk in planktonic organisms. Current conservation status is listed as Not Evaluated. Its ecological significance lies within the broader context of marine microbial food webs, where haptophytes serve as primary producers and food sources for zooplankton and protozoans.
