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.

Chrysochromulina limonia is a species of marine haptophyte microalga in the genus Chrysochromulina, family Chrysochromulinaceae, class Prymnesiophyceae. The specific epithet limonia, derived from Latin for lemon-yellow, likely references the characteristic golden-yellow coloration of the cells or a particular pigmentation pattern observable under light microscopy. Chrysochromulina species are golden-brown algae whose color arises from the combination of chlorophylls a and c with fucoxanthin and other carotenoid pigments within their chloroplasts. C. limonia has been recorded from Norwegian and Swedish coastal marine waters, contributing to the substantial representation of this genus in northern European phycological collections and literature. Norwegian fjords and coastal shelf habitats provide cold, seasonally productive conditions where Chrysochromulina species frequently constitute a significant fraction of the nanoplankton community. Like its congeners, C. limonia is a small, free-living pelagic organism that engages in photosynthesis and potentially mixotrophy, and it bears the characteristic haptonema structure alongside two flagella. Cell surface scales, whose morphology is visible under electron microscopy, provide the primary characters for distinguishing C. limonia from other species in the genus. The haptonema, when extended, can exceed the cell body in length and assists in temporary attachment or prey capture. C. limonia has not been evaluated under IUCN criteria and carries a conservation status of Not Evaluated. It represents one component of the rich haptophyte diversity that characterizes Scandinavian coastal marine microflora.
