Common Mussurana – This venomous reptile can be found throughout the bulk of South America, and grows to about 7 feet in length. They are found primarily in forestlands near water, and they are often seen swimming in the river. They are rear fanged snakes that are only mildly venomous. Among venomous pet snakes, this one is a common target for owners.
Lancehead – Commonly called a fer-de-lance, the lancehead is among the most dangerous snakes in the world. Though their venom is not the most powerful in the world by any means, they are around people. Lots of people. This leads to a large number of snakebites, and the bite is a serious enough one to kill. Because of this, the South American population fears this snake. They are great at hiding in camo, and will not hesitate to bite when cornered or bothered. They grow to about five feet long and have long fangs to deliver their venomous bite.
Western Coral Snake – This snake is not often encountered, and is very similar to the species found in the United States. The coral snake is ringed with red, yellow and black down the length of their body, and they have small rear fangs to deliver venom. While the bites are rare, coral snake bites are very serious. A coral snake is a member of the cobra family.
Bushmaster – The longest viper in the world is also the most feared by South Americans and with good reason. The Bushmaster is a very large (9 ft) venomous snake, that is not shy about biting and injecting a deadly venom. The thing about the bushmaster is, that even if you get medical help, you might still pass away from a serious bite. They are also masters at staying hidden, so many people never see them until it is too late. Also, this large snake delivers a large amount of venom to go along with that bite, so it is a very bad thing to get bitten.
