Cheetah

지구상 가장 빠른 육상 동물로, 아프리카와 이란의 초원에서 단거리 질주 시 시속 112km에 달하는 속도를 낸다. 깊은 가슴, 긴 다리, 독특한 흑색 눈물 줄무늬를 가진 날씬한 체형이 특징이다. 다른 대형 고양이과와 달리 치타는 지저귀는 소리와 그루링 소리를 낸다. 서식지 파편화와 대형 포식자와의 경쟁으로 인해 약 7,000마리만 남아 있으며 취약종으로 분류된다.

Chroomonas mesostigmatica is a species of cryptophyte alga in the family Chroomonadaceae, described from freshwater environments. The specific epithet mesostigmatica likely refers to a centrally positioned stigma — a photoreceptive structure — within the cell, distinguishing this species morphologically from others in which the stigma is positioned differently. The stigma or eyespot in flagellate algae is associated with photoreception, enabling the cell to orient its swimming direction toward or away from light sources in a process called phototaxis. This capability is ecologically important for optimizing position in the water column relative to light availability and nutrient distribution. Chroomonas species are biflagellate, swimming with characteristic rapid, slightly helical motility. The cells contain cryptophyte-type plastids with phycobiliproteins and chlorophyll a and c. Chroomonas mesostigmatica has been documented from European freshwater habitats, contributing to the diverse microalgal communities of lakes, ponds, and slow-flowing waters. Its ecological roles include primary production and participation in the microbial loop through grazing by heterotrophic flagellates. The species has not been assessed by the IUCN.
