Ballena azul

El animal más grande que se conoce haya vivido en la Tierra; las ballenas azules pueden alcanzar 33 metros y 200 toneladas — sus corazones solos pesan tanto como un automóvil pequeño. Se encuentran en todos los océanos y migran entre las zonas de alimentación polares y las áreas de reproducción tropicales. Son filtradoras que consumen hasta 4 toneladas de kril al día. En peligro de extinción, con poblaciones globales estimadas entre 10.000 y 25.000 tras casi extinguirse por la caza de ballenas en el siglo XX.

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.
