JACKSONVILLE, Fla. - If the Atlantic Ocean had a "most wanted" list, one fish in particular would probably be at the top.
The lionfish is native to the Indo-Pacific, but in recent years it has made its way to southern and northeastern Florida.
Experts believe people are dumping the lionfish in the ocean after it becomes too big for their aquariums.
"While they might think that is the right thing to do, that is actually the worst thing they could do," said Joe Kistel with Think It Sink It Reef It, a wildlife non-profit in Jacksonville.
The problem is the lionfish has no natural predator, meaning no other animal is eating it.
Instead, it is eating a lot of baby fish other animals and humans depend on in many ways.
For instance, Kistel said the lionfish likes to prey on baby grouper. That interrupts the ocean's food chain, the species' reproductive cycle and the ability for fishermen to stay in business.
