Marine Wildlife Encyclopedia Lionfish Pterois volitans Although
the lionfish can inflict a painful sting, it is not dangerous to
humans. Its flamboyant coloration of red stripes serves as a
warning both to divers and to would-be predators. Also known as
the turkeyfish, the lionfish hunts at night using its winglike
pectoral fins to trap its prey of fish, shrimp, and crabs
against the reef.
