Sssamy accepted her first fuzzy today

YES I am a happy man.
I went thru the book 'reptiles and amphibians for dummies' by Patricia Bartlett, she says on page 240 that boas and pythons have visible cloacal spurs that are noticeably larger on males than on females.
Got the same info here:
Ball Pythons ( I hope it is OK to show URL) and here
Ball Python - Royal Python Information Sheet
But here, it says the opposite
Untitled Document
and as a conclusion
ADW: Python regius: Information
I do not want to start a war here, it is just that I am getting contradicting info...

.... not easy to make my mind as a rookie
