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。

Cobetia amphilecti is a halophilic, gram-negative bacterium belonging to the family Halomonadaceae within the class Gammaproteobacteria. First characterized from marine and saline environments, this aerobic rod-shaped organism thrives in conditions of elevated salinity that would inhibit the growth of most other bacteria. Like other members of the genus Cobetia, it possesses a sophisticated osmotic stress response system that accumulates compatible solutes—primarily ectoine and hydroxyectoine—to balance intracellular osmotic pressure against hypersaline surroundings. Cobetia amphilecti has been isolated from coastal marine sediments and saline water samples across the Indo-Pacific region, with documented collections from Taiwanese coastal habitats. The organism is motile by means of a single polar flagellum and is capable of utilizing a broad range of organic compounds as sole carbon and energy sources, including various carbohydrates and amino acids. Its metabolic versatility allows it to occupy diverse niches in marine biogeochemical cycles, particularly in the degradation of organic matter in high-salinity environments. As a member of Halomonadaceae, Cobetia amphilecti is of biotechnological interest for its production of ectoine, a commercially valuable extremolyte used in cosmetics and pharmaceuticals for its cellular protective properties. The species has not been formally assessed for conservation status by the IUCN.
