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 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.
