The approach I favor: Simply look quizzically at the person as though he's a bug under your microscope, note his more bizarre qualities, and silently classify him as a Mephitis mephitis (striped skunk) or Agkistrodon
contortrix mokeson (northern copperhead).
Three species: cottonmouth (Agkistrodon
piscivorus; 49.8%), rough green snake (Opheodrys aestivus; 15.9%), and gray ratsnake (Pantherophis spiloides; 10.7%) comprised 76.5% of snakes encountered from 2003 2008.
Viperidae, subfamily Crotalinae, includes the Crotalus genus (rattlesnakes), Agkistrodon
genus (copperheads and cottonmouths) and the Bothrops genus (Ferdelance).
