地球上で生きたことが知られている最大の動物であるシロナガスクジラ（Balaenoptera musculus）は、体長33メートル、体重200トンに達することができ、心臓だけで小型自動車ほどの重さがあります。全ての海洋に生息し、極地の餌場と熱帯の繁殖地の間を回遊します。1日最大4トンのオキアミを摂取する濾過摂食者です。20世紀の捕鯨による絶滅危機からの回復後、世界的な個体数は10,000〜25,000頭と推定される絶滅危惧種です。

Chitinophaga taiwanensis is a species of Gram-negative, aerobic bacterium belonging to the genus Chitinophaga in the family Chitinophagaceae. As the specific epithet indicates, this species was first described from soil samples collected in Taiwan. Like all members of Chitinophaga, it possesses the enzymatic machinery to degrade chitin — the structural polysaccharide abundant in fungal cell walls, insect cuticles, and crustacean shells — making it a key participant in the terrestrial nitrogen and carbon cycles. The genus is characterised by gliding motility on semi-solid or solid surfaces, production of pigmented colonies (typically yellow, orange, or tan), and a strictly aerobic metabolism. C. taiwanensis thrives in the rich agricultural and subtropical soils of Taiwan and similar environments, where the turnover of fungal biomass and arthropod debris provides abundant chitin substrate. Research on Chitinophaga species from tropical and subtropical soils has advanced understanding of chitinolytic enzyme diversity and its applications in biocontrol of soil-borne fungal diseases affecting crops. As a bacterium, Chitinophaga taiwanensis is not assessed under IUCN Red List criteria, which are designed for animals, plants, fungi, and other eukaryotes. The species' ecological significance lies in its contribution to soil health, organic matter decomposition, and nitrogen mineralisation in agricultural and natural ecosystems.
