Synura Ehrenberg
	From Greek syn, "together" + oura, "tail"
	Synura forms swimming colonies from a variable number of cells joined together at their posterior ends in a spherical or elongated cluster. In colonies of only a few cells, the cells are usually more spherical in shape, while in larger colonies the cells are normally club-shaped and packed more tightly together. Each cell has two flagella that protrude along the edge of the colony to permit a rolling, tumbling, swimming motion. The cells have two parietal, golden-brown chloroplasts that contain the pigments chlorophyll-c1 and fucoxanthin. A large storage vacuole is sometimes visible in the cell posterior. Unlike Ochromonas, Synura and other synurophytes do not possess eyespots.   Like all synurophytes or scaled chrysophytes, the cells are covered in siliceous scales. In most Synura species, and in most of the synurophytes, the scales form ordered, overlapping rows arranged in a spiral pattern on the cell surface. Synura scales have secondary layer of silica with larger distal pores and siliceous ribs. Most of the anterior scales have spines. Large cells of Synura petersenii have about 90 scales.
