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 crustatorum is a halophilic gram-negative bacterium in the family Halomonadaceae, closely related to other salt-tolerant members of the genus Cobetia. This aerobic, chemoorganotrophic organism was originally described from saline crustacean-associated environments, with its species epithet 'crustatorum' referring to its association with crustaceans. Like its congeners, C. crustatorum is adapted to thrive in environments with sodium chloride concentrations well above those tolerable by most mesophilic bacteria, typically growing optimally at 5–15% NaCl. The organism exhibits the characteristic gram-negative cell wall architecture and typically appears as short rods or ovoid cells under microscopy. Cobetia crustatorum has been documented from coastal Taiwanese marine habitats, where it participates in the decomposition of organic materials in saline sediments and associated with marine invertebrates. It produces extremolytes such as ectoine that protect cellular machinery from osmotic stress and desiccation. The organism is aerobic and motile, using polar flagella for locomotion in its aqueous saline environment. Taxonomically, the genus Cobetia was reclassified from Halomonas following phylogenetic analyses that revealed distinct evolutionary lineages within the broader Halomonadaceae family. Research on Cobetia species is ongoing due to their potential applications in biotechnology, particularly for biosurfactant and extremolyte production in industrial settings. Conservation status has not been evaluated by the IUCN.
