Which pythons lack heat pits?

[Tigergenesis]

So far I've come up with the following:

~ Black Headed Python
~ Woma

I had originally thought (going by one of my books) that the
Ringed Python & Papuan Python lacked pits, but someone corrected me and said they do.


It seems these are the only ones - or am I mistaken? Just curious.
Just trying to correct/update the book.

Thanks

either they dont have them or they just are obvious to me, but do bloods have them?

Yes Bloods have them & other than Womas & Blackheads there are no others that I know of that don't. Mark I.
