Anacondas are the largest of all snakes. They are known for their massive size. A normal Anaconda can grow up to 50 to 100 feet long. They spend most of their time in water in search of food.The records tell us that even the great Indian python is smaller than the record Anaconda. But the girth of Anaconda is larger than any snake. Though the anaconda's size is said to be 50 to 100 feet, no one has caught the giant snakes and measured anywhere near that size.Anacondas kill their prey by squeezing or crushing to death and making the prey die of internal bleeding.Then the snake swallows the victim as a whole. They eat caimans much like alligator, other snakes, deer, and even jaguars. Some snakes has venom in their teeth but anacondas are not venomous.They use their size to kill their prey.
