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 limonia is a species of marine haptophyte microalga in the genus Chrysochromulina, family Chrysochromulinaceae, class Prymnesiophyceae. The specific epithet limonia, derived from Latin for lemon-yellow, likely references the characteristic golden-yellow coloration of the cells or a particular pigmentation pattern observable under light microscopy. Chrysochromulina species are golden-brown algae whose color arises from the combination of chlorophylls a and c with fucoxanthin and other carotenoid pigments within their chloroplasts. C. limonia has been recorded from Norwegian and Swedish coastal marine waters, contributing to the substantial representation of this genus in northern European phycological collections and literature. Norwegian fjords and coastal shelf habitats provide cold, seasonally productive conditions where Chrysochromulina species frequently constitute a significant fraction of the nanoplankton community. Like its congeners, C. limonia is a small, free-living pelagic organism that engages in photosynthesis and potentially mixotrophy, and it bears the characteristic haptonema structure alongside two flagella. Cell surface scales, whose morphology is visible under electron microscopy, provide the primary characters for distinguishing C. limonia from other species in the genus. The haptonema, when extended, can exceed the cell body in length and assists in temporary attachment or prey capture. C. limonia has not been evaluated under IUCN criteria and carries a conservation status of Not Evaluated. It represents one component of the rich haptophyte diversity that characterizes Scandinavian coastal marine microflora.
