Chrysamoeba

Chrysamoeba is a genus of golden algae, belonging to the order Chrysomonadida. These are microscopic, aquatic organisms, often found as single cells or in colonies. They possess one or two anterior flagella, typically near a red eyespot, and contain yellowish or brown pigments within their chromatophores. Most Chrysamoeba species are photosynthetic, though some can gather food using pseudopodia. They can lose their flagella and adopt a cyst-like or palmellar form. Reproduction occurs through asexual division, and they commonly form cysts enclosed in a siliceous wall.1
