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.

Chrysochromulina megacylindra is a unicellular marine haptophyte microalga in the genus Chrysochromulina, class Prymnesiophyceae, order Prymnesiales. The species epithet megacylindra — from Greek meaning large cylinder — refers to a prominent cylindrical element of the cell's scale ornamentation, distinguishing it from related species such as C. brachycylindra, whose epithet denotes a short cylinder, and C. microcylindra, with a small cylinder. This naming pattern reflects the systematic use of scale morphology to differentiate species within the genus. C. megacylindra has been recorded from Norwegian and Swedish coastal marine waters, contributing to the known diversity of Chrysochromulina in northern Atlantic environments. The species inhabits the photic zone of coastal marine systems, where it functions as a photosynthetic primary producer. Chrysochromulina cells in this size class typically range from five to twenty micrometers in greatest dimension and are counted among the nanoplankton — a size fraction particularly important in oligotrophic and post-bloom marine ecosystems. The coiling haptonema of C. megacylindra, like that of all Chrysochromulina species, likely assists in prey capture or substrate attachment, enabling mixotrophic nutrition in environments where dissolved nutrients are limiting. The species has not been assessed under IUCN criteria and is classified as Not Evaluated. Its documentation contributes to understanding the high species richness within Chrysochromulina and the role of nanoplankton diversity in northern European marine ecosystems.
