Python vs. Boa — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Updated on March 16, 2024
Pythons are non-venomous snakes known for their size and constricting method of prey capture, while boas are also non-venomous, but differ in habitat and certain physical features.

Key Differences
Pythons and boas are both large, non-venomous snakes that kill their prey through constriction. While they share similarities in behavior and appearance, they belong to different families: Pythonidae for pythons and Boidae for boas. This distinction is important because it reflects their different evolutionary paths, habitat preferences, and, in some cases, physical characteristics.
Pythons are primarily found in Africa, Asia, and Australia, demonstrating a wider geographic distribution in mainly tropical regions. On the other hand, boas are native to North, Central, and South America, as well as some islands in the Caribbean. This difference in habitat influences their adaptation and survival strategies, with each group developing unique characteristics suitable for their environments.
One of the main physical differences between pythons and boas is the presence of pelvic spurs. Pythons retain these vestigial remnants of hind limbs, which can be seen near their cloaca. Boas also have these spurs, but they are generally less pronounced. These spurs are used during mating to stimulate the female and are a visible sign of their evolutionary past.
Reproduction is another area where pythons and boas differ. Pythons are oviparous, meaning they lay eggs. The female python will often stay with the eggs until they hatch, using her body to generate heat and incubate them. Boas, on the other hand, are mostly ovoviviparous, giving birth to live young. This reproductive strategy reflects adaptations to their specific environmental conditions.
In terms of diversity, both families boast a wide range of species. However, pythons tend to have a slightly greater diversity in size, with some species, like the reticulated python, being among the longest snakes in the world. Boas, while also varying in size, generally do not reach the lengths of the largest pythons. This difference in size can affect their prey choices, habitats, and predation risks.
