白头海雕

白头海雕是美国国鸟，也是美国生态保护史上的成功案例，曾因滴滴涕（DDT）的广泛使用而濒临灭绝，经保护措施的实施后种群数量已显著恢复。该物种在IUCN红色名录中被评估为无危（LC），以白色头颈和尾羽与深棕色体羽形成的鲜明对比为主要识别特征。它们主要以鱼类为食，也会捕食哺乳动物和腐肉。

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.
