Chrysochromulina acantha是一种单细胞定鞭藻，细胞表面覆有长刺状鳞片，外观独特。它栖息于温带和寒冷大洋水域的海洋浮游环境中。这种混合营养微藻既能进行光合作用，也能吞噬细菌获取补充营养。

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.
