THE LARGEST& HEAVIEST SNAKE
The largest snake in the world, by weight atleast, is the Anaconda, or Eunectes murinus, of South America. Green Anacondas, also known as water boas, are considered to be the heaviest. The biggest snakes of these species can grow to be up to 35 feet long and can weigh up to 1,000 pounds. Their camoflage coloring makes them very difficult to spot in their natural habitat and snakes this large are very rarely seen but claims of snakes 60 to 150 feet have been made.
