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 spinifera is a marine haptophyte alga in the family Prymnesiaceae, distinguished by spine-bearing scales on the cell surface, from which the epithet spinifera (Latin: spine-bearing) derives. These spines, visible under electron microscopy, project outward from the organic scale body, giving cells a bristled appearance. Chrysochromulina species produce these complex scale structures internally and export them through the endomembrane system. Cells are biflagellate and equipped with a haptonema used in prey capture and attachment. C. spinifera is found in coastal marine waters of temperate and cold seas in the Northern Hemisphere, consistent with the broader biogeographic range of the genus. Haptophytes of the Chrysochromulina type play significant roles in marine ecosystems as primary producers, bacterivores, and sources of biochemically important compounds including polyunsaturated fatty acids and DMSP. Some Chrysochromulina species produce haemolytic compounds during bloom events that are toxic to fish and invertebrates. The conservation status of C. spinifera has not been evaluated by the IUCN, and the species is listed as Not Evaluated. Molecular phylogenetics is gradually resolving the taxonomy of the numerous spine-bearing Chrysochromulina morphospecies.
