Brazilian Sharpnose Sharks Off Brazil Coast Test Positive for Cocaine
Jul 22, 2024, 11:09 PM
Scientists have discovered that Brazilian sharpnose sharks in waters off the coast of Brazil, particularly near Rio de Janeiro, have tested positive for cocaine. Marine biologists believe the drug likely entered the ecosystem through the city's sewerage system, potentially altering the sharks' behavior. The phenomenon has been dubbed 'Cocaine Sharks' and is causing concern among researchers about the environmental impact and the potential danger to humans. It is suspected that smugglers dumping their stash in the water may have contributed to this issue.
