However, when present in high enough numbers, some varieties may be noticeable as colored patches on the water surface due to the presence of </span>chlorophyll<span> within their cells and accessory pigments (such as </span>phycobiliproteins<span> or </span>xanthophylls<span>) in some species.</span>
