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.

jaguar

アメリカ大陸最大のネコ科動物で、体重は最大100kgに達し、がっしりとした筋肉質の体型と特有のロゼット模様の毛皮を持つ。メキシコから南アメリカにかけて分布し、アマゾンやパンタナルが主要生息地となる。優れた水泳能力を持つ頂点捕食者であり、獲物個体数の調節に重要な役割を担う。森林破壊により生息域が縮小し、準絶滅危惧に分類されている。
