A CBS News Report reveals sharks in the waters off Brazil have tested positive for cocaine.
The story notes 13 Brazilian sharpnose sharks were taken from the coast off of Rio de Janeiro and tested for the cocaine and benzoylecgonine, the primary molecule in cocaine.
“Each shark’s liver and muscles tested positive for high levels of cocaine, the study found, and the female sharks tested had higher concentrations of cocaine in their muscles than male sharks. ”
A 2023 movie called “Cocaine Shark” made fun of the idea but sadly they are real, just not ravaging the oceans eating people as the movie of course played up.
This is obviously tragic on several levels. First off that cocaine is so prevalent as it’s obviously fueling a gigantic human demand and also that it is impacting sharks and other ocean life.
It will be interesting to see if further studies indicate how cocaine and other drugs impact fish behavior.
While tagging sharks early in my career our boat was hit with a big wave from a crew boat servicing the oil rigs.
All three of us onboard were thrown as the boat nearly capsized. So was the shark I was tagging.
It landed on my calf and bit me.
It was a three foot long Atlantic sharpnose shark, the close cousin to the Brazilian sharpnose found with cocaine in its system in this new study.
My leg ended up being fine but the little guy did bite down with power.
I’m just glad it wasn’t all coked up
That bite might’ve been worse.
