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 peptidivorans is an anaerobic, endospore-forming bacterium in the family Clostridiaceae specialized in the fermentation of peptides and amino acids, as indicated by the species epithet meaning 'peptide-devouring.' It was isolated from anaerobic environments rich in proteinaceous material, including oil field brine waters and sediments where complex organic nitrogen compounds are abundant. Like all clostridia, it is a strictly anaerobic, Gram-positive, rod-shaped bacterium that forms resistant endospores. C. peptidivorans uses Stickland fermentation reactions — coupled oxidation and reduction of amino acid pairs — to derive energy from peptide and amino acid substrates, producing organic acids, ammonia, and other end products. The ability to metabolize peptides makes it an active participant in the anaerobic degradation of protein-rich organic matter in subsurface environments. Its discovery in oil field environments suggests that peptidivoranous clostridia play roles in the anaerobic cycling of organic nitrogen in deep subsurface biotopes, contributing to biogeochemical processes in petroleum-associated anaerobic microbial communities.
