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。

Clostridium sporogenes is an anaerobic, endospore-forming bacterium in the family Clostridiaceae phylogenetically and morphologically closely related to C. botulinum type A but lacking the genes encoding botulinum neurotoxin. It is widely distributed in soil, sediments, and the gastrointestinal tracts of animals and humans, where it is considered a non-pathogenic member of the microbiome. The species epithet sporogenes refers to its characteristic production of abundant, conspicuous endospores. C. sporogenes is highly proteolytic, producing multiple proteases that break down proteins into amino acids and peptides, contributing to the decomposition of organic nitrogen in anaerobic environments. In food science, it serves as a surrogate organism in studies validating thermal processing conditions for low-acid canned foods — its heat-resistant spores are used as surrogates for C. botulinum in process safety testing without the biosafety concerns of using the toxigenic parent species. Research has also explored C. sporogenes as a vector for delivering anticancer prodrug-activating enzymes into hypoxic tumor microenvironments, exploiting its preferential germination in anaerobic tissue regions.
