  2. Boa snakes are ovoviviparous animals meaning they live birth to live animals whereas Python snakes are oviparous, meaning they lay eggs that hatch into snakes.
  3. Boas are known as New World snakes as they are found in America, and Pythons are known as Old World Snakes as they are found in Asian countries.
  4. Boas often have red marking near their tail and that is why they are also known as Red-tailed snakes. But pythons do no necessarily have red tails.

Boa and Pythons are some of the largest snakes in the world. They both are non – venomous and kill their prey by constricting them. Both are the biggest constrictor. Boa’s and Pythons both have a life span of about 20-30 years, and feed on warm-blooded animals and mammals, and have the special pit on their tongue to sense rising heat when their prey arrives.
