The image on the top shows Ceratium trichoceros (in the middle) with three horns of almost the same length. C. furca has three straight horns. C. tripos (on the left side).

Blooming
When a net sample contains homogenous species in great abundance, we talk about blooming. The blooming of dinoflagellates can happen in summer and early autumn.
