Chrysochromulina spinifera is a marine haptophyte alga in the family Prymnesiaceae, distinguished by spine-bearing scales on the cell surface, from which the epithet spinifera (Latin: spine-bearing) derives. These spines, visible under electron microscopy, project outward from the organic scale body, giving cells a bristled appearance. Chrysochromulina species produce these complex scale structures internally and export them through the endomembrane system. Cells are biflagellate and equipped with a haptonema used in prey capture and attachment. C. spinifera is found in coastal marine waters of temperate and cold seas in the Northern Hemisphere, consistent with the broader biogeographic range of the genus. Haptophytes of the Chrysochromulina type play significant roles in marine ecosystems as primary producers, bacterivores, and sources of biochemically important compounds including polyunsaturated fatty acids and DMSP. Some Chrysochromulina species produce haemolytic compounds during bloom events that are toxic to fish and invertebrates. The conservation status of C. spinifera has not been evaluated by the IUCN, and the species is listed as Not Evaluated. Molecular phylogenetics is gradually resolving the taxonomy of the numerous spine-bearing Chrysochromulina morphospecies.

コウテイペンギン

世界最大のペンギンであるコウテイペンギン（Aptenodytes forsteri）は体高最大1.2m、体重45kgで、地球上で最も過酷な環境の一つである南極大陸に生息しています。零下60°C以下の真冬の暗闇の中で繁殖し、雌が海上にいる間、雄が65日間足の上で育雛嚢の下に一つの卵を温め続けます。数千羽からなる群れで個体が暖かい中心部を循環するいわゆるハドリング行動は、協調的な生存戦略の傑作です。
