Chrysochromulina strobilus is a marine haptophyte microalga in the family Prymnesiaceae. The specific epithet strobilus (Greek/Latin: pine cone or spinning top) likely references the conical arrangement of scales on the cell surface or the overall cell shape observed under microscopy. Like all members of the genus, C. strobilus is biflagellate and bears a haptonema, the defining appendage of the class Haptophyta. The organic scales covering the cell exterior are of species-specific morphology, serving as the primary character for species-level identification. C. strobilus inhabits marine photic-zone environments, with records from northern European and Scandinavian coastal waters. Chrysochromulina species collectively constitute a significant fraction of marine nanoplankton biomass and contribute to carbon fixation, dissolved organic matter production, and the microbial food web. Some congeners produce dimethylsulfoniopropionate and haemolytic toxins relevant to sulfur cycling and harmful algal events, respectively. The IUCN has not assessed the conservation status of C. strobilus, and it is classified as Not Evaluated. Its global distribution and population structure remain subjects of ongoing environmental survey and molecular studies.
