Wild sharks off the coast of Brazil have tested positive for cocaine, according to new study by Brazilian scientists, in the latest research to demonstrate how illegal drug consumption by humans is harming marine life.
According to a study entitled Cocaine Shark and published in the journal Science of the Total Environment, scientists dissected the bodies of 13 sharpnose sharks (Rhizoprionodon lalandii) caught in fishermen’s nets off a beach in Rio de Janeiro.
