Chrysochromulina adriatica is a species of haptophyte alga in the family Prymnesiaceae, described from the Adriatic Sea. Haptophytes are a distinctive group of marine and freshwater eukaryotic algae characterized by the possession of a haptonema — a coiling appendage between the two flagella that serves in prey capture or substrate attachment. The genus Chrysochromulina is one of the most species-rich genera of haptophytes, with over a hundred described species. Chrysochromulina species are typically covered with elaborate organic scales, the intricate structure of which is used for species identification, often requiring electron microscopy. Members of the genus are found in marine and brackish environments worldwide and can be significant components of the nano- and picoplankton. Most species are mixotrophic, capable of both photosynthesis and phagotrophy. Some Chrysochromulina species, such as Chrysochromulina leadbeateri and Prymnesium parvum (a related genus), are known for the production of toxic compounds during bloom events that have caused fish kills in coastal and aquaculture settings. Chrysochromulina adriatica, described from the Adriatic Sea, contributes to the diverse marine microalgal community of the Mediterranean basin. The species has not been assessed by the IUCN.

Chrysochromulina mantoniae is a marine haptophyte alga named in honor of the pioneering British phycologist Irene Manton, whose electron microscopic studies of algal flagella and scales transformed the taxonomy of nanoplankton in the mid-twentieth century. The species belongs to the family Prymnesiaceae and displays the characteristic Chrysochromulina body plan: two heterodynamic flagella, a haptonema of variable length, and a cell surface coated with organic scales. C. mantoniae inhabits coastal marine waters of the North Atlantic, consistent with the geographic range of most formally described Chrysochromulina species. As a planktonic photosynthesizer and potential mixotroph, it contributes to the cycling of carbon and nutrients in the marine microbial food web. The haptonema's role in cell adhesion and prey capture has been studied extensively in closely related species, revealing complex behaviors including coiling and extension dynamics. The IUCN has not evaluated the conservation status of C. mantoniae, classifying it as Not Evaluated. This reflects the general absence of threat assessment methodology for free-living marine microorganisms whose populations are shaped largely by oceanographic rather than anthropogenic drivers.
