Chroomonas vectensis is a species of cryptophyte alga in the family Chroomonadaceae, with the specific epithet vectensis suggesting a type locality or particularly strong association with the Isle of Wight (Vectis in Latin), off the southern coast of England. If correctly attributed, this would place the type collection in the coastal or brackish waters of the Isle of Wight or surrounding seas, suggesting this species may be adapted to marine or brackish conditions, as opposed to the strictly freshwater Chroomonas species. Marine cryptophytes are significant contributors to coastal phytoplankton and are important prey items in marine food webs. Chroomonas vectensis would share the general characteristics of the genus — small biflagellate unicells with a cryptophyte plastid bearing phycobiliproteins and chlorophyll a and c — while potentially possessing adaptations to saline or brackish conditions such as osmotic regulation mechanisms. Marine cryptophytes have received increasing scientific interest for their potential as sources of EPA (eicosapentaenoic acid), a valuable polyunsaturated fatty acid. Conservation status has not been assessed by the IUCN.
