Ceratium fusus are dinoflagellates, approximately 200-300µm long and 15-30µm wide. These singular cells are fusiform in shape with one end of the cell slightly tapering and curving towards the left, while the other end slightly tapering and curving towards the right. Linear markings are found towards the middle of the cell.
Ceratium fusus are found in temperate and tropical waters.
