Lionfish (Pterois volitans)

Lionfish are the apex invasive predators of the Caribbean, consuming over 30 species of native fish and crustaceans with voracious appetites that reduce juvenile fish populations by up to 79% on invaded reefs. With no natural predators in the Atlantic, a single lionfish can spawn over 2 million eggs per year, outpacing #7 European Rabbit's reproductive rate by 40%. Their venomous spines and explosive growth make them 50% more resilient than typical reef fish, enabling them to dominate ecosystems from Florida to Brazil.
