What is the difference between a Boa Constrictor and a Python?

Pythons have an extra bone in their head and more teeth than boa constrictors. Another difference between the two snakes is that pythons lay their eggs while boas give birth to live young. Boa constrictors incubate eggs inside their bodies and give birth to as many as 60 babies.

Boas and pythons are both constrictors, wrapping their body around their prey until suffocation is achieved. Neither boas nor pythons are venomous and typically only attack people when threatened. Some people in South America are actually known to keep boas loose in their homes to control rat infestations. Boas are carnivores and grow to around 13 feet long and 100 pounds in weight.
