Bamboo bear

ジャイアントパンダ（Ailuropoda melanoleuca）は中国中部の山岳竹林に生息し、体重最大125キログラムになるクマ科の動物で、食肉目に分類されながら食事の99%を竹が占める特異な食性を持つ。偽の親指（橈側種子骨）を使って竹の茎を把握し、1日14時間もの採食時間を費やす。2016年にIUCNレッドリストで絶滅危惧から危急（VU）へ改善されており、保護繁殖プログラムと自然保護区の設置が個体数回復に貢献している。

Chrysochromulina scutellum is a marine haptophyte microalga belonging to the family Prymnesiaceae. The species epithet scutellum (Latin: small shield) describes the shield-like shape of the distinctive scales adorning the cell surface. These organic scales, produced internally in Golgi-derived vesicles and subsequently exported to the plasma membrane, form a protective and taxonomically informative outer coat. Cells are biflagellate with a haptonema, allowing both swimming and temporary attachment to solid surfaces or prey organisms. C. scutellum is found in coastal and offshore marine environments, with documented records from northern European seas. Haptophytes of the Chrysochromulina type are photosynthetic nanoflagellates that utilize chlorophylls a and c, fucoxanthin, and related pigments for light harvesting. The DMSP produced by many haptophytes, including Chrysochromulina species, is a critical component of the marine sulfur cycle and acts as an antioxidant, cryoprotectant, and grazing deterrent. C. scutellum has not been formally assessed by the IUCN and is categorized as Not Evaluated. Understanding the true geographic and genetic diversity of this species and its congeners requires expanded environmental molecular surveys.
