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.

Emperor Penguin

세계에서 가장 큰 펭귄인 황제펭귄(Aptenodytes forsteri)은 키가 최대 1.2m에 몸무게가 45kg에 달하며, 지구상에서 가장 혹독한 환경인 남극 대륙에 서식합니다. 영하 60°C 이하의 한겨울 암흑 속에서 번식하며, 수컷이 암컷이 바다에 있는 동안 65일 동안 발 위에서 육아낭 아래에 알 한 개를 품습니다. 수천 마리가 모인 무리에서 개체들이 따뜻한 중심부를 순환하는 이른바 허들링 행동은 협동적 생존의 훌륭한 사례입니다.
