Morphology: Motile cells are strongly metabolic and possess a brown plastid with a red-orange eyespot located near the flagellar insertion. The naked posterior flagellum is rigid , the anterior flagellum is flexible and covered by hairs and knob scales , and an emergent haptonema is present between the flagella. Sections of whole cells demonstrate the high degree of plasticity of cell shape, from compressed to long. There is also variability in nuclear shape. A pulsate vacuole is present at the centre of the cell, showing a relation with the flagellar pit. The plastid has parallel thylakoid lamellae, a bulging pyrenoid and an eyespot on the inner face, adjacent to a less osmiophilic zone connected with the flagellar pit. [Bendif et al. 2011]
