자이언트판다(Ailuropoda melanoleuca)는 중국 중부 산지 대나무 숲에 서식하는 흑백의 상징적인 곰으로, 몸무게는 최대 125kg에 달하며 하루 최대 14시간을 대나무 섭취에 소비합니다. 식육목에 속함에도 불구하고 식이의 99%가 대나무이며 대나무 줄기를 잡기 위한 위족지(의사 엄지)를 가집니다. 성공적인 보전 및 번식 프로그램 덕분에 2016년 위기(EN)에서 취약(VU)으로 하향 조정되었습니다.

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.
