Cheetah

地球上で最も速い陸上動物で、アフリカとイランの草原において短距離走で時速112kmに達する。深い胸部、長い脚、独特の黒い涙縞模様を持つ細身の体型が特徴だ。他の大型ネコ科動物とは異なり、チーターはチャープ音やパー音で鳴く。生息地の分断と大型捕食者との競争により、残存個体数は約7,000頭のみとなっており、危急種に分類されている。

Chrysochromulina inornamenta is a marine haptophyte microalga in the genus Chrysochromulina, class Prymnesiophyceae. The species epithet inornamenta — meaning unornamented — is particularly notable within a genus where most species are distinguished by elaborate scale ultrastructure. This name suggests that C. inornamenta either lacks the complex scale ornamentation typical of its congeners or possesses unusually simple scale morphology, making it an atypical member of the genus and potentially useful for understanding the evolution of scale complexity in haptophytes. C. inornamenta has been recorded from Norwegian and Swedish coastal marine waters, the primary region from which Chrysochromulina species diversity has been characterized through electron microscopy surveys. Norwegian and Swedish coastal environments include productive fjord systems and shelf waters supporting rich microplankton communities. Like other members of the genus, C. inornamenta is presumed to be a photoautotrophic or mixotrophic nanoplankton organism, capable of photosynthesis using chlorophylls a and c and associated carotenoid pigments. It possesses the characteristic haptophyte haptonema alongside two flagella. The haptonema coiling behavior distinguishes Chrysochromulina from the related genus Prymnesium. C. inornamenta has not been formally assessed under the IUCN Red List framework and carries a conservation status of Not Evaluated. Its existence highlights that even within a well-studied genus like Chrysochromulina, morphological diversity encompasses both highly ornamented and comparatively plain cellular phenotypes.
