Chrysolykos complanatus is a freshwater chrysophyte microalga in the genus Chrysolykos, class Chrysophyceae. The species epithet complanatus — flattened or compressed — describes a lorica that is notably flattened in lateral view compared with the more three-dimensional forms of other Chrysolykos species. This flattened lorica morphology is the primary taxonomic character distinguishing C. complanatus from the angular C. angulatus and the boot-shaped C. calceatus within the small genus Chrysolykos. The loricate chrysophytes, including Chrysolykos, are characterized by cells enclosed within a species-specific outer case from which two flagella emerge — one directed anteriorly and one often wrapped around the cell — enabling swimming in aquatic environments. C. complanatus has been recorded from Norwegian and Swedish freshwater ecosystems, contributing to the known diversity of chrysophytes in cold Scandinavian lakes and pond habitats. These boreal and subarctic freshwater environments, often characterized by low pH, low nutrient concentrations, and high dissolved organic carbon from surrounding peat bogs, support characteristic chrysophyte assemblages in which loricate forms are frequently present. The species contributes to primary production as a photoautotroph and may supplement its carbon budget through bacterivory. Chrysolykos species are minor components of most phytoplankton communities and are not known to form blooms. C. complanatus has not been evaluated under IUCN Red List criteria and is listed as Not Evaluated.

Chrysolykos planctonicus is a planktonic chrysophyte flagellate in the genus Chrysolykos, a small genus of loricate or semi-loricate golden algae in the class Chrysophyceae. Like other Chrysolykos species, it inhabits the open water column of freshwater lakes and ponds, where its planktonic lifestyle is reflected in the specific epithet planctonicus. The cell is typically enclosed in a lorica or cellulose housing that may be less rigid than those of Chrysococcus species, with a flagellum extending through an apical pore. Chrysolykos species are photosynthetic and potentially mixotrophic, using chlorophylls a and c and fucoxanthin-type carotenoids for light energy capture. The genus is documented from Scandinavian freshwaters and other northern temperate lakes, where chrysophytes are often the dominant flagellated algae in spring and early summer. C. planctonicus contributes to primary production in oligotrophic and mesotrophic lake systems. The species has not been evaluated for conservation status by the IUCN and is listed as Not Evaluated. Chrysolykos is a less-studied genus than Chrysococcus or Mallomonas, and its ecology and phylogeny remain incompletely characterized.
