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。

Colacium vesiculosum is a freshwater euglenoid protist in the family Euglenaceae, exhibiting the characteristic sessile colonial growth of the Colacium genus. Distinguished by vesicle-like or bladder-shaped colony structures, this species attaches to the exoskeletons and appendages of zooplankton hosts, particularly copepods and cladocerans, in standing and slow-moving freshwater bodies. As a photosynthetic euglenoid, Colacium vesiculosum possesses green chloroplasts enabling autotrophic energy acquisition under illuminated conditions, supplemented by heterotrophic nutrient uptake when light is limited. The organism does not penetrate host tissues and is considered epibiotic rather than parasitic, though dense colonization may influence host buoyancy and movement efficiency. Colacium vesiculosum contributes to the microbial component of freshwater planktonic communities, serving as potential food for filter-feeding organisms and influencing nutrient recycling in aquatic ecosystems. Its global distribution spans temperate and tropical freshwater habitats, bounded primarily by the availability of suitable crustacean hosts. Taxonomy within Colacium remains an active area of research as molecular tools refine species boundaries that were historically defined by morphological characteristics alone.
