🇧🇷🦈 Brazil is dealing with cocaine sharks. A new study examining 13 wild sharks caught in fishing nets near Rio de Janeiro found all of the sharks had high levels of cocaine in their blood, muscles, and liver. Previous studies have found traces of cocaine in local river, sea, and sewage water, as well as in other sea creatures like shrimp – though officials say it’s unclear where the drug originated. Scientists have yet to conduct any studies on whether cocaine damages sharks’ health or affects their behavior – though Hollywood probably has its own ideas already (coming soon: Cocaine Shark, a sequel to Cocaine Bear).
