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。

Chitinophaga sancti is a soil-dwelling bacterium within the genus Chitinophaga, family Chitinophagaceae, phylum Bacteroidota. The genus Chitinophaga encompasses a diverse group of Gram-negative, aerobic, rod-shaped to filamentous bacteria with a defining metabolic hallmark: the ability to degrade chitin using secreted chitinase enzymes. Chitin is a ubiquitous biopolymer in terrestrial and aquatic ecosystems, forming the structural component of fungal cell walls, nematode egg shells, and insect and crustacean exoskeletons. By mineralising chitin, Chitinophaga species play an indispensable role in releasing bound nitrogen and carbon back into bioavailable forms in the soil. C. sancti, like other members of this genus, exhibits gliding motility — a form of movement across solid surfaces without flagella — and typically forms flat, spreading colonies with a characteristic pigmentation on laboratory culture media. Its name may reference a type locality or the specific source environment from which it was described. As a prokaryote, this species is not evaluated under IUCN criteria, which apply to eukaryotic organisms of conservation concern. Nevertheless, soil bacterial diversity including species like C. sancti represents a vital but often overlooked dimension of biodiversity, underpinning ecosystem services upon which agriculture and natural ecosystems depend.
