The world’s most venomous fish (that we know of) is also, terrifyingly, an expert at camouflage. Found in oceans from the Red Sea to Australia’s Great Barrier Reef, they lurk on the seabed and blend in almost completely with the reefs and rocks. From those hidden depths they ambush their prey and, while they don’t hunt out humans, their venom can prove deadly to those unlucky enough to step on one. The poison, injected from the dorsal fin spines, can kill within an hour if the anti-venom isn’t administered.
