Invasive lionfish, which have no native predators, have wreaked havoc in Florida and the Caribbean—and have now spread to Brazil.
Lionfish are one of the most pernicious invasive species swimming in today’s oceans. And now, they’ve made it as far south as Brazil on their continuing and destructive territorial expansion.
Lionfish have been migrating south for years. They were first caught in the Gulf of Mexico, likely released from the aquarium trade, in 1985, and quickly expanded into U.S. East Coast and the Caribbean. They reached South American coastlines around 2010.
