In the December 2001 Limnology and Oceanography, Karin Rengefors of Lund University and Catherine Legrand of the University of Kalmar, both in Sweden, report that the freshwater dinoflagellate Peridinium aciculiferum also produces at least one toxin. In contrast to its marine counterparts, P. aciculiferum uses the agent offensively.
