Chrysochromulina elegans is a species of golden-brown haptophyte microalga in the genus Chrysochromulina, family Chrysochromulinaceae, class Prymnesiophyceae. The epithet elegans — meaning elegant or graceful — refers to the refined morphology of the cell and its surface ornamentation, likely reflecting the delicate arrangement of organic scales characteristic of this species. Chrysochromulina cells are typically spherical to ovoid, with two equal flagella and a coiling haptonema that is longer than the flagella in many species, giving the cell a distinctive triaxial appendage arrangement. C. elegans has been recorded from Norwegian coastal waters, consistent with the historical pattern of Chrysochromulina species discovery in Scandinavian phycological surveys. Norwegian coastal and fjordic environments provide cold, productive waters where haptophyte diversity is high, particularly during spring blooms and summer thermal stratification. The species is a phytoplankton organism functioning as a primary producer and potential prey item for heterotrophic protists, copepod nauplii, and other zooplankton. Chrysochromulina species collectively contribute to oceanic biogeochemical cycles through carbon fixation, dimethylsulfoniopropionate production, and participation in the microbial loop. C. elegans has not been assessed under IUCN criteria and is listed as Not Evaluated. Improved molecular phylogenetic methods continue to refine the taxonomy of the genus, and future studies may clarify the global distribution and ecological roles of C. elegans relative to its congeners.
