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 parva is a small haptophyte microalga belonging to the genus Chrysochromulina in the family Prymnesiaceae. The specific epithet parva (Latin: small) denotes its cell dimensions relative to other congeners. Structurally, cells possess two unequal flagella and a haptonema, the three-membrane-bound appendage that defines the class Haptophyta and provides the genus with its feeding and attachment capabilities. Organic scales cover the entire cell surface, and their ultrastructure is examined by electron microscopy for species identification. C. parva inhabits marine photic-zone waters in temperate and cold seas, where it forms part of the nanoplankton community. Haptophytes as a group contribute substantially to global marine primary production and produce significant quantities of dimethylsulfoniopropionate (DMSP), a compound with important implications for climate regulation via its atmospheric breakdown product dimethylsulfide. C. parva has not been formally assessed for conservation status and is listed as Not Evaluated by the IUCN. Like most free-living protists, it lacks the discrete geographic range limits that make conventional threat categorization applicable. Molecular surveys continue to expand knowledge of Chrysochromulina diversity in undersampled ocean regions.
