Chrysochromulina quadrikonta is a marine haptophyte microalga in the genus Chrysochromulina, class Prymnesiophyceae. The specific epithet quadrikonta derives from Greek roots meaning four appendages or four-pointed, likely describing a scale form with four projections or a four-pointed spine structure on the cell surface, a morphological character used to distinguish it from other species in the genus. The Chrysochromulina scale repertoire includes simple plates, scales with spines, scales with cylinders, and various complex three-dimensional forms, and four-pointed configurations occur among several species. C. quadrikonta has been recorded from Norwegian coastal marine environments, continuing the pattern of Chrysochromulina species concentration in Scandinavian waters that has emerged from decades of electron microscopy-based phycological surveys. Norwegian coastal habitats including fjords, estuaries, and open shelf areas support rich microalgal communities in which haptophytes are frequently abundant. The species is a nanoplankton organism capable of photosynthesis through the standard prymnesiophyte pigment system, and likely engages in mixotrophic nutrition supplementing photosynthate with bacterivory. The haptonema, coiled or extended depending on physiological state, is a key functional organelle enabling prey detection and capture. C. quadrikonta has not been evaluated under IUCN Red List criteria and is classified as Not Evaluated. Continued molecular and morphological studies of Norwegian Chrysochromulina populations will further clarify species boundaries and global distribution patterns within this diverse genus.
