In 1985, the first invasive lionfish was spotted off Florida after aquarium releases; within decades, it had spread across much of the Caribbean and US Atlantic coast, devastating reef fish that had no natural defense against it

A single lionfish spotted in Florida in 1985 has spiraled into one of the most alarming marine invasions. These venomous, fast-reproducing Indo-Pacific fish, likely released from aquariums, have decimated native fish populations across the Western Atlantic and Caribbean. Their unchecked spread threatens vital fisheries and coral reefs, impacting economies that millions depend on. Eradication is unlikely, with focus now on management and developing a market for lionfish as food.
