Do Snakes Sneeze?

One expert we contacted told us this: "Snakes don't sneeze with their mouths shut, but they do clear fluid from their throat with an explosive blast of air from the lungs."
Snakes don't sneeze very often, though. In fact, a few herpetologists we contacted denied that snakes sneeze at all. But another expert we contacted insisted otherwise: Snakes sneeze for the same reason as other vertebrates--to clear their respiratory passages. Snakes rarely sneeze, however, and people who keep them in captivity know that sneezing in snakes is usually a sign of respiratory illness resulting in fluid in the air passage.
