Our main conclusion is that D. norvegica, and probably all other species from the genus Dinophysis, is mainly phagotrophic and feeds on a larger prey than T. amphioxeia. Autotrophy through kleptoplastidy would be a secondary feature used as a complementary or short-term survival strategy. Place, publisher, year, edition, pages Elsevier B.V , 2008.

Due to the increasing prevalence of Dinophysis spp. and their toxins on every US coast in recent years, the need to identify and monitor for problematic Dinophysis populations has become apparent. Here, we present morphological analyses, using light and scanning electron microscopy, and rDNA sequence analysis, using a ~2‐kb sequence of ribosomal ITS1, 5.8S, ITS2, and LSU DNA, of Dinophysis

Dinophysis acuta is a photosynthetic species with yellow chloroplasts (Dodge, 1982, Larsen and Moestrup, 1992). Dimorphic cells, one half resembling D. acuta and the other half resembling D. dens (the proposed gamete form), have occasionally been observed in this species (Reguera et al., 1990, Hansen, 1993, Moita and Sampayo, 1993).

Dinophysis acuminata and D. norvegica have mainly been abundant from March to December, whereas D. acuta has typically occurred in late summer and autumn (August-December). For all three species we have observed a narrowing of the peak season since 2002 at the same time as they have become less abundant.

It was first described in 1839 by Christian Gottfried Ehrenberg. Dinophysis are typically medium-sized cells (30-120 µm). The structural plan and plate tabulation are conserved within the genus.
