Red Lionfish

Pretty much everything about the venomous red lionfish—its red-and-white zebra stripes, long, showy pectoral fins, and generally cantankerous demeanor—says, "Don't touch!"

The venom of the red lionfish, delivered via an array of up to 18 needle-like dorsal fins, is purely defensive. It relies on camouflage and lightning-fast reflexes to capture prey, mainly fish and shrimp. A sting from a lionfish is extremely painful to humans and can cause nausea and breathing difficulties, but is rarely fatal.

Red lionfish are native to the reefs and rocky crevices of the Indo-Pacific, although they've found their way to warm ocean habitats worldwide.

The largest of lionfish can grow to about 15 inches in length, but the average is closer to 1 foot.
