Chroococcus cumulatus is a cyanobacterium in the family Chroococcaceae, found in freshwater and semi-aquatic habitats. Members of the genus Chroococcus are among the simplest organized cyanobacteria, consisting of spherical cells that divide by binary fission to form pairs or tetrads held together within layered gelatinous sheaths. Cyanobacteria are cosmopolitan prokaryotes that carry out oxygenic photosynthesis using pigments including chlorophyll a, phycocyanin, and phycoerythrin. Chroococcus species occur in diverse aquatic habitats ranging from standing freshwater bodies to damp soil surfaces, rock faces, and tree bark in humid environments. The genus has historically been characterized primarily on the basis of cell size, sheath structure, and colony organization, though molecular analysis has increasingly revealed cryptic diversity within morphologically defined groups. Chroococcus cumulatus has been documented from northern European freshwater habitats. As a microscopic prokaryote, it has not been assessed by the IUCN, and its ecological role centers on primary production at the base of aquatic food webs in its habitat.

koala

オーストラリア東部・南東部を代表する有袋類で、体重は最大15kgに達し、低カロリーのユーカリの葉食から得るエネルギーを節約するために1日最大22時間を睡眠に費やす。他の哺乳類の多くを死に至らしめる有毒なユーカリ成分を処理するために高度に特化しており、解毒に特別に適応した腸内微生物叢を持つ。クラミジア感染症、生息地の伐採、気候変動により個体数が激減し、2022年に絶滅危惧種に指定された。
