Chroomonas (crow-owe-moan-ass) is one of the cryptomonad flagellates with blue-green plastids. The inclusions are mostly polysaccharide (starch) storage. Two flagella are visible at top (anterior) and the cell surface is irregular because of the small skeletal plates that lie under the cell membrane. With posterior pyrenoid. This may be Chroomonas mesostigmata. Differential Interference Contrast.
