LIMA does not justify the use of punishment in lieu of other effective interventions and strategies. Dinoflagellates of the genus Prorocentrum, most closely related to the genus Dinophysis, were first characterized by Ehrenberg in 1833.Species of Prorocentrum can be planktonic, benthic, or epiphytic and are distributed globally, most diversely in tropical or sub-tropical marine environments. One of their main characteristics is having a latitudinal variability and an assimilation/retention specific for each species. Pollo a la brasa.
