That seems like a decent start. My guess is boas being "new world" snakes are slightly less primitive? Only a guess, but it seems live young as opposed to egg laying shows some advancement.

I am not wanting to talk myself out of our B/P by any means, but I like some of the info on the boas as far as being inquisitive and having seemingly better vision.

I'd be interested to know in general if boas have bigger or better functioning brains. I have seen some huge beautiful pythons.

There is a tiger reticulated on you tube that is in my opinion one of the most beautiful snakes I've seen. I think it's a 21 footer and the owner takes her out to show some friends. Her head is huge, but I wonder how the brain compares to a huge boa. Obviously knowing size of subject doesn't equal huge brain

Just looking to find out more. I'll read as people answer. I'm really into this stuff now thanks to my son.
