The difference between difference between types of snakes

[Skiploder]

I think what what we are looking for is how they are broken down.

Don't remember the exact number but I think it's like 85-95% of the world's snakes are constrictors so the breakdown I believe you may be looking for goes something like this:

Never mind, Trackstrong beat me to it.




Sidenote/question: Aren't some venomous snakes considered colubrids?

Two thirds of all snakes are colubrids. Colubridae is the great taxonomic dumping ground for snakes. Unclassified snakes are often moved into this family only to be moved to another one further down the road as they are studied in greater detail.

For example, rhamphiophis are a genus of colubrid that will probably moved to elapidae in our lifetime, even though they are rear fanged.
