Chrysochromulina acantha es un alga haptófita unicelular con escamas largas en forma de espinas en la superficie celular, confiriéndole un aspecto espinoso distintivo. Habita ambientes planctónicos marinos en aguas oceánicas templadas y frías. Esta microalga mixotrófica realiza fotosíntesis y también puede fagocitar bacterias para obtener nutrición suplementaria.

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.
