This fish gets its name from its stone-like appearance. This excellent disguise allows it to blend in with the background as it wait for its prey, small fish, to wander close enough to gobble. In addition to its gruesome looks, the stonefish has sharp, venomous spines that contain enough poison to kill a man. Frogfishes get their name from their grotesque, almost frog-like appearance. Their strange looks help to camouflage them as they wait to catch their prey.
Frogfishes have a specially modified dorsal spine with a fleshy growth at the end.
They lie motionless and use this spine like a fishing rod. When a curious fish gets too close, it is swallowed up instantly by large, powerful jaws. Scorpionfishes are characterized by their bizarre appearance and the numerous spines that cover their bodies. Similar to the lionfish, these spines contain venom strong enough to cause a very painful wound and even more serious injury to those who may have allergic reactions. The strange appearance of the scropionfish helps conceal them as they wait to ambush their prey.
