Dinophysis is a genus of dinoflagellates common in tropical, temperate, coastal and oceanic waters. It was first described in 1839 by Christian Gottfried Ehrenberg. Dinophysis are typically medium-sized cells (30-120 µm).

In contrast, D. norvegica was the most abundant and most frequently observed Dinophysis species in outer Oslofjorden in this study (see below).
