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 terrae is a soil bacterium within the genus Chitinophaga, family Chitinophagaceae, phylum Bacteroidota. The epithet terrae — meaning 'of the earth' or 'of the soil' — aptly describes this species' ecological niche as a terrestrial, soil-dwelling organism. Chitinophaga terrae shares the defining characteristics of the genus: Gram-negative cell morphology, gliding motility, strictly aerobic respiration, and the production of extracellular chitinases capable of hydrolysing chitin. These chitinolytic enzymes break down the long-chain polysaccharide into shorter oligomers and ultimately into N-acetylglucosamine monomers, which can then be assimilated as carbon and nitrogen sources by the bacterium and other soil inhabitants. This metabolic activity positions C. terrae as an important contributor to the decomposer community of terrestrial soils, facilitating nutrient cycling particularly in environments with high inputs of fungal and arthropod biomass. Like other Chitinophaga species, it is non-pathogenic and has been identified in a range of agricultural and natural soils globally. Industrial interest in the genus centres on chitinase production for biotechnological applications including biological pest control, biodegradable material production, and enzyme formulations for various industries. As a bacterium, C. terrae is outside the scope of IUCN assessments and is listed as Not Evaluated.
