Although most snakes, turtles, lizards and other reptiles typically pose little threat to humans, some can be numbered among the deadliest creatures on the planet. The most dangerous among them can be determined by evaluating data from zoos, animal researchers and other scientific sources. 1:Alligator Snapping Turtle: While turtles are mostly harmless, these 2-foot-long turtles weigh more than many humans -- males can weigh as much as 220 pounds -- and have strong jaws that can amputate the fingers or limbs of anyone who gets too close. Reticulated Python i found throughout southeast Asia, the reticulated python can weight more than 350 pounds and reach lengths of 30 feet. The snake's size matters because it kills by constriction so its mass literally squeezes victims to death by suffocation. 2:agama lizard florida: The Agama picticauda lizards are colorful — especially when they are breeding — and can grow to about a foot. red headed lizard florida are dangerous they can kill humans 3:Fer-de-Lance This pit viper found throughout Central and South America is not only venomous but highly aggressive. While most snakes bite only once to conserve their venom, the fer-de-lance will strike multiple times. According to the BBC, half of all bites in Costa Rica are delivered by this large reptile. 4:Eastern Brown Snake Australia holds the distinction for being home to the most types of venomous snakes, with more than 50 species. However, more than three-fourths of all snakebites on the continent are delivered by the eastern brown snake. Although its venom is deadly and can cause paralysis within minutes, improved anti-venom availability means this snake kills only one or two people every year. 5:Black Mamba What makes the black mamba so dangerous is not just its powerful venom. The snake is also fast: it can slither at a rate of more than 12 miles per hour, meaning it can outrun most humans. Another dangerous aspect of this snake is its location. Most humans encounter black mambas in rural areas of Africa, so reaching anti-venom and medical treatment in time is not always possible. Without treatment, the black mamba's poison is fatal within 20 minutes. Sent from my TECNO KC2 using Tapatalk
