African elephant

地球上最大の陸上動物であるアフリカゾウは体重7,000 kgに達し、サハラ以南のサバンナ、森林、湿地に生息する。成熟した雌が群れを率いる高度に知的な社会構造を持ち、超低周波音やうなり声、接触によって意思疎通する。木を引き倒したり水飲み場を掘ったり種子を散布したりすることで生態系を形成するエンジニア種だが、象牙の密猟や生息地の喪失により個体数は減少しており、危急（VU）とされている。

Chrysochromulina apheles is a marine haptophyte microalga in the genus Chrysochromulina, family Chrysochromulinaceae, class Prymnesiophyceae. Members of this genus are distinguished by their coiling haptonema, two flagella of approximately equal length, and a covering of organic scales on the cell surface — features used extensively in species identification through electron microscopy. C. apheles inhabits coastal marine environments and has been recorded from Norwegian and Swedish waters, regions where intensive phycological surveys during the late twentieth century yielded numerous new haptophyte species descriptions. These subarctic and temperate Atlantic coastal waters sustain diverse nanoplankton communities in which Chrysochromulina species are frequently abundant components. The epithet apheles derives from Greek, referencing a morphological characteristic of the cell or scale structure. As a phytoplankton organism, C. apheles participates in primary production, converting inorganic carbon to organic matter through photosynthesis, and may also engage in phagotrophy of bacterial cells. Some Chrysochromulina species produce polyunsaturated fatty acids and occasionally bioactive compounds. The taxon has not been evaluated under IUCN criteria and carries a conservation status of Not Evaluated, reflecting the general challenge of assessing extinction risk in free-living marine microalgae whose populations are cosmopolitan and difficult to census. Understanding the ecology and distribution of species like C. apheles contributes to knowledge of marine microbial diversity and the functioning of pelagic food webs in northern Atlantic ecosystems.
