Stonefish feed on crustaceans and small fish. The stonefish primarily hunts in reefs and has strong camouflage abilities, emulating the rocks and reef in which it dwells, making it a dangerous predator for its prey.

The exterior spines of the stonefish are highly venomous and can lead to neurotoxic poisoning, which can assist in catching prey, but can also be deadly to humans, as stated by WebMD's eMedicine Health. Stonefish also boast large mouths, and when well camouflaged the fish can easily suck up their prey as it draws near. The stonefish is found in the Pacific Ocean and the Indian Ocean, and typically lies dormant on the sea floor or in reefs.
