Great on the book! It is well written and has fantastic photos.
Unless you also had the same results I just listed above, "field study" or some other wording does in fact help.
I changed wording again moments ago and was able to find this.

And this.

This actually has a breakdown of the different types of teeth and their niche in hunting various prey.
I understand you were asking a general question. It appeared that you were only getting information unrelated to pythons/boas and not finding your answer.
when i tried to look this up just now it became most frustrating because the focus was on snakes in general and it was just “gaboon viper blah blah”
That's why suggested trying some different wording.
I was simply offering advice to you, and anybody else that switching some wording can produce different results.
