Sharks off the coast of Florida may be consuming cocaine that is being dropped into the ocean by drug smugglers, according to researchers. The US Coast Guard recently reported seizing over 6,400 kilograms (14,109 pounds) of cocaine in the Caribbean Sea and Atlantic Ocean in just one month. Scientists working on the Discovery Channel’s upcoming TV series ‘Cocaine Sharks’ have observed strange behaviors in sharks in the area and conducted experiments to investigate further.
Tom Hird, a marine biologist, and Tracy Fanara, an environmental scientist from the University of Florida, have been studying the effects of cocaine on sharks in the Florida Keys. Fishermen in the area have reported encountering drug-addicted fish, prompting the researchers to investigate. During one dive, Hird and Fanara witnessed a great hammerhead shark, a species known to avoid humans, aggressively swimming towards them in an abnormal manner. They also observed a sandbar shark swimming in tight circles, seemingly fixated on something that wasn’t there.
In one experiment, the scientists placed a dummy swan next to a package resembling a real cocaine bale that would have been dropped by drug smugglers. Surprisingly, rather than attacking the swan, the sharks immediately went for the fake cocaine, attempting to take bites out of the package. In fact, one shark managed to grab the entire bale and swim away with it. The researchers also created a bait ball using highly concentrated fish powder, which triggered a dopamine rush in the sharks similar to the effects of cocaine. The sharks exhibited wild, erratic behavior after consuming the powder.
Hird commented, “I think we have got a potential scenario of what it may look like if you gave sharks cocaine. We gave them what I think is the next best thing. [It] set [their] brains aflame. It was crazy.”
The researchers also conducted a simulated drug drop by dropping fake cocaine packages from an airplane. They discovered that multiple shark species instantly moved towards the packages. However, it is important to note that the study has not confirmed whether sharks are actually consuming cocaine. The researchers admit that they have no idea what cocaine could do to the sharks, but they hope that the airing of their documentary series will generate more research on this topic and shed light on how other pharmaceuticals affect marine life.
This study highlights the potential impact of drug trafficking on marine ecosystems. The presence of illegal drugs in the ocean could have unforeseen consequences for marine predators like sharks. Further research is needed to fully understand the extent of this issue and its implications. Additionally, this research opens up discussions about the broader effects of pharmaceuticals on marine life, prompting the need for more investigation in this area. The documentary series ‘Cocaine Sharks’ aims to raise awareness about this issue and promote further research into the effects of drugs on marine organisms.
