Something most folks don't know about sanzinia is that they have beaded scales on their heads. In fact close up shots would be confused for stone gardens or polished aggregate in cement. I don't know any other snake that has these scales to this extent.

Thing is, this baffles me completely. I have no idea what sort of evolutionary relic this might be for, or even if it has modern advantages.

I'd love to hear what you guys think could be the reason for these beaded irregular scales.
