The World's Most Venomous Fish | Australia's Deadly Monsters

Exploiting flooded estuaries, the stonefish is an unlikely predator. An awkward swimmer, he's simply not built for the chase. Just getting from point A to point B is an arduous task. So actively chasing down prey is not a viable option. This monster's approach is more passive-aggressive. Camouflage is his strong suit. Once he finds the right spot, he'll remain sedentary for some time. He'll even tolerate algae growing on his rough skin as it enhances concealment. In his element, it's obvious why the stonefish is so named. He is virtually indistinguishable from his surroundings. And all he has to do is wait. He's an ambush predator. And patience is the name of his game. In these brackish waters rich in prey, he doesn't have to wait long for a potential meal to drift into his kill zone. Despite those big bulbous eyes, his presence goes unnoticed. Timing, when the element of surprise is your key weapon, is everything. If he strikes too soon, the fish are alerted to his presence. But wait too long, and they fin out of range. But once the fish strays within optimum striking distance, he launches an accurate and lightning-fast assault. The unwary fish never saw it coming.
