The Deadliest Creatures (Most Easy to Miss) he deadliest (and easy to miss) critters lurk in dark silence, ready to strike with either the barest of warnings or none at all - and with absolutely fatal venom. 1. The Cone Snail: can kill you in less than 4 minutes Say, for instance, you happen to be happily walking through the low surf merrily picking up and discarding shells, looking for just the right one to decorate your desk back at the office. With no warning at all, however, you feel a sharp sting from one of those pretty shells -- a sting that quickly flares into a crawling agony. With that quick sting, the cone snail's barbed spear has insidiously injected you with one of the most potent neurotoxins in existence. 2. Poison Arrow Frog: Lethal Touch That frog over there, for instance: that tiny, brilliantly colored tree frog. Doesn't he look like some kind of Faberge ornament, there against that vermilion leaf? Wouldn't such a natural jewel look just gorgeous in a terrarium back home? Pick him and you'll be dead in a matter of minutes. One second frolicking in the undergrowth, the next spasming and foaming on the jungle floor. No stinger, no bite, no venom: just the shimmering slime covering his brilliant body They are the only animal in the world known to be able to kill a human by touch alone. They can jump as far as 2 inches."
