Phytoplankton of the month - March 2016

Ceratium furca

Ceratium furca are large dinoflagellates, approximately 70-100µm long and 30-50µm wide. The cell is widest at the girdle. C. furca’s epitheca tapers to one point, while its hypotheca extends into two unequal points, where the right is shorter than the left. This organism sometimes blooms in the late summer to early fall. Ceratium lineatum looks similar to C. furca, but is much smaller in size (30-60µm long and 25-45µm wide).

Ceratium furca are found in temperate and tropical waters.
