Campeche, Mexico. July 1, 2016.
In his epic The Amphibians and Reptiles of the Yucatán, Julian Lee speculates that Sibon may derive from the Latin sibonis, a kind of hunting spear. The specific epithet nebulatus derives from the Latin nebula, or ‘cloud’; it seems only right to photograph this snake off the ground. Given their diet of slugs and snails, Sibon nebulatus likely spend part of their lives in bushes and trees.
