 Speculations of sexual dimorphism that is the difference between the female and male counterparts have allowed researchers to draw conclusion that species of this genus can undergo sexual reproduction[1].The first record of DSP with Dinophysis acuminata and Dinophysis fortii was in 1980 in the Patagonian coast[4].A year after the report, another occurrence of DSP unleashed in December 1993 and November 1994[4].
