Scientists from the Cape Eleuthera Institute and international allies have analyzed blood samples from 85 sharks and found illicit substances, stimulants, or drugs.
This would be the first time in the world that scientific research reveals caffeine and acetaminophen in sharks, as reported this Thursday by local media, and they would be the first specimens from the Bahamas with cocaine and diclofenac.
The substances were found in 28 of the 85 sharks from different parts of Eleuthera, a remote island located 80 kilometers east of Nassau, the capital of the Bahamas.
Caffeine has been the main component, in 27 sharks, while acetaminophen has been reflected in three, cocaine in two, and diclofenac in three of the species from which samples have been taken.

Of all the places where scientists have conducted the study, The Aquaculture Cage has recorded the highest concentration of chemicals in Caribbean reef sharks.
The Aquaculture Cage is frequented by boats for diving or tour operators for excursions and thus to dive with sharks, which could contribute to the pollution of these environments.
The findings are significant, as they play a critical role in the maintenance of marine ecosystems, and in the Bahamas specifically, the tourism industry is supported through marine conservation and shark diving.
Although scientific research has not shown that the substances found inside sharks have caused them any physical or health damage, it has found differences between the biological markers of contaminated and non-contaminated animals.
