Malayan pit viper
This snake, act surprised, has a reputation for being ill-tempered and quick to strike. I said, act surprised, what you though they were all cute and cuddly? It can be found in Southeast Asia.
Jararaca
The Jararaca is probably one of the best-known venomous snake that can be found in wealthy and heavily populated areas of southeastern Brazil. In fact, between 1902 and 1945, this snake was responsible for just over 52% (3,446 cases) of snakebites, with a 0.7% mortality rate (25 deaths).
