Chrysochromulina camella is a marine haptophyte microalga belonging to the genus Chrysochromulina within the family Prymnesiaceae. Cells are spherical to ovoid, biflagellate, and equipped with a haptonema of variable length used in capturing bacterial prey. The cell surface is ornamented with a layer of unmineralized organic scales whose shape and arrangement constitute important diagnostic features at the species level. C. camella is a component of the marine nanoplankton assemblage, occupying photic-zone waters where it participates in primary production and the microbial loop. The genus has been most thoroughly studied in the coastal waters of Scandinavia, where numerous species were first described by the Norwegian phycologist Parke and others during the mid-twentieth century. Some Chrysochromulina species form episodic blooms that can release ichthyotoxic compounds, causing mortality in fish farms and wild fish populations. The ecological and taxonomic status of C. camella has not been formally evaluated by the IUCN, and the species is classified as Not Evaluated. Ocean acidification and warming represent potential long-term stressors for haptophyte communities globally.

Chrysochromulina cymbium is a unicellular haptophyte alga in the class Prymnesiophyceae. Its species epithet, cymbium (Latin: small boat), likely references cell morphology visible under light microscopy. Like all Chrysochromulina species, it possesses two heterodynamic flagella and a haptonema — the coiling, thread-like appendage unique to haptophytes that functions in prey capture and temporary surface attachment. The cell surface bears organic scales arranged in overlapping tiers, observable under electron microscopy. C. cymbium is a photosynthetic nanoflagellate found in coastal marine environments, where it contributes to primary productivity and carbon cycling. Scandinavian waters have historically yielded the greatest diversity of described Chrysochromulina species, reflecting intensive phycological survey effort in Norway, Sweden, and Denmark. The genus as a whole includes species capable of toxin production during bloom events, posing risks to aquaculture. No formal conservation assessment has been conducted for C. cymbium; it is listed as Not Evaluated by the IUCN. Advances in metabarcoding have revealed that environmental diversity within Chrysochromulina far exceeds the number of formally described morphospecies.
