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。

Cocconeis pinnata is a marine and brackish-water diatom in the family Cocconeidaceae, distinguished within the genus by the pinnate (feather-like) arrangement of its striae and the specific valve morphology of its silica frustule. As an adnate epiphyte, C. pinnata attaches to a wide variety of substrates in coastal and estuarine environments, including seagrass blades, macroalgal surfaces, sandy sediments, and biogenic hard substrates such as shells and coral rubble. The species has been documented from tropical and subtropical marine habitats across the Indo-Pacific and Atlantic, with records from South American coastal waters as well as other warm marine regions. Cocconeis pinnata plays a significant ecological role in seagrass ecosystems, where epiphytic diatom communities including this species form a productive biofilm layer on leaf surfaces that serves as food for grazing invertebrates, sea urchins, and small fish. In areas of excessive nutrient loading, however, proliferation of epiphytic algae including diatoms can shade out the underlying seagrass, contributing to meadow decline. The production and dissolution of silica frustules by marine benthic diatoms contributes to the benthic silica cycle, linking biological productivity with the geochemistry of shallow coastal sediments. Species-level identification of Cocconeis taxa requires electron microscopy due to subtle morphological differences. Conservation status has not been formally assessed.
