Trimorphodon tau tau
Sonora, Mexico. August 21, 2011
My first tau was a neonate, a young of the year, and I saw many more like it while road-cruising southern Sonora in late August, along with an occasional adult. On some nights, the neonate tau were the most common snakes on the road. If you look closely at the neonate’s tongue, you will note it is semi-transparent.
