The Lionfish is a colorful fish that can grow up to 15 inches long, has venomous spines that can paralyze or kill its prey like small fish and shrimp, and lives in coral reefs in the Pacific and Indian Oceans. It relies on camouflage and fast reflexes to hunt, and its stripes warn predators that it is poisonous, though humans, eels and frogfish prey on lionfish.
