Sharks might be consuming drugs that are dumped off the Florida coast, scientists say.
An upcoming Shark Week episode will investigate whether the drugs are impacting the animals.
The scientists observed unusual behavior from some sharks, including one fixating on an imaginary object.
If these cocaine bales are a point source of pollution, it's "very plausible" sharks can be affected by this chemical, Fanara said.
The scientists created packages that resembled cocaine bales and dropped them into the water to see how the sharks would respond.
