Cover Story: A massive Ostreopsis cf. ovata bloom was described in Currais Archipelago, a poorly studied region in the subtropical Brazilian coast (Southwest Atlantic Ocean). The bloom was similar to harmful events recurrently reported in the Mediterranean Sea, with O. cf. ovata cells from both regions sharing the same genotype and similar toxin intracellular quotas and profile. Moderate toxin concentrations accumulated in edible mussels during the bloom, and toxic cells of O. cf. ovata attached to different types of plastic litters that are commonly ingested by sea turtles, indicating a potential for environmental and public health damages in this area.
