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 pringsheimii is a haptophyte microalga in the family Prymnesiaceae, named for the German botanist Nathanael Pringsheim, who made foundational contributions to algal biology in the nineteenth century. The species follows the Chrysochromulina body plan: a biflagellate cell with a haptonema and a surface coat of organic scales arranged in overlapping layers. Scale morphology observed under electron microscopy provides the principal characters used to distinguish C. pringsheimii from related species. The species is found in marine and occasionally brackish coastal waters of northern Europe, consistent with the biogeographic concentration of described Chrysochromulina diversity in Scandinavian seas. As a nanoplankton primary producer, it participates in carbon fixation and the transfer of photosynthetically fixed carbon to higher trophic levels via grazing by heterotrophic nanoflagellates and microzooplankton. Some Chrysochromulina species produce dimethylsulfoniopropionate, contributing to the oceanic sulfur cycle. The conservation status of C. pringsheimii has not been evaluated by the IUCN, and the species is listed as Not Evaluated. Global environmental sequencing suggests that the diversity of haptophyte nanoflagellates in the world's oceans greatly exceeds what has been formally described.
