Description Small to medium species, almost oval or elliptical in shape. Posterior profile is rounded. Left sulcal list well developed, extends beyond the midpoint of the cell, and is of equal depth. Surface with areolae, each with a pore. [details] DistributionDinophysis acuminata is widely distributed from cold to warm waters of both hemispheres. Its presence in the Mediterranean Sea has not been convincingly demonstrated. [details] Harmful effect The main agent of DSP outbreaks in European Atlantic coasts. Also associated with DSP outbreaks in NE Japan and New Zealand. In recent years, first report of DSP outbreaks associated with blooms of this species in NW (Esenkulova & Haigh 2012) and NE North America (Hattenrath-Lehmann et al. 2012).
Producer of okadaic acid (OA), dinophysis toxins (DTXs)—toxins implicated in DSP outbreaks—and pectenotoxins (PTXs). Some strains appear to produce only PTX (Nielsen et al. 2012), others only OA (Fernández et al. 2001), others DTX1 and PTX2 (Suzuki et al. 2009) or a mixture of OA, DTXs and PTXs (Miles et al. 2004).

D. acuminata and D. acuta are the main DSP toxin producers in Europe (Reguera et al. 2012) [details] IdentificationDinophysis acuminata is smaller than D. acuta and the most antapical rib of the sulcal wing is not directed antapically. Dinophysis norvegica has a different shape of the hyposome.

[details] Habitat pelagic [details] Importance General: known for producing dangerous toxins, particularly when in large numbers, called "red tides" because the cells are so abundant they make water change color. Also they can produce non-fatal or fatal amounts of toxins in predators (particularly shellfish) that may be eaten by humans.
