Chrysochromulina acantha is a microscopic marine haptophyte alga belonging to the family Prymnesiaceae. Like other members of the genus Chrysochromulina, it possesses two flagella of unequal length and a unique organelle called the haptonema, which is used for prey capture and surface attachment. The cell surface is covered with organic scales arranged in overlapping layers, a diagnostic feature of the genus. C. acantha is a unicellular phytoplankton found in coastal and open-ocean environments, contributing to marine primary productivity. Members of this genus are known from temperate and cold-water seas of the Northern Hemisphere, particularly Scandinavian coastal waters. Some Chrysochromulina species can form dense blooms under favorable nutrient conditions, occasionally producing toxic compounds harmful to fish and invertebrates. The species has not been formally assessed by the IUCN, and its conservation status remains Not Evaluated. As a free-living microorganism, it does not face the same threats as larger organisms, though shifts in ocean chemistry and temperature may influence its distribution and abundance over time.
