The Eastern hognose snake, also called "puff(ing) adder", is a harmless snake found in Indiana. Do not confuse it with the real puff adder, which is a highly venomous viper. It is a totally different species found in Africa.
Snakes in Indiana
There are roughly 39 taxa of snakes that are native to Indiana, while some prefer wooded areas, others occupy wetlands or marshes. So the question now is how many of the 39 are venomous? Well, there are only 4 venomous snakes. They are:
  1. Timber Rattlesnake
  2. Eastern Massasauga
  3. Northern Copperhead
  4. Western Cottonmouth

These poisonous snakes are basically pit vipers and can be identified by the following characteristics. These identification characteristics although may not present be present in each snake, but they can surely help:
  • Heat-sensing pits (behind the nostril)
  • Wider heads and narrower necks
  • Heavy bodies; they appear stout/fat
  • Spade-shaped head
  • Elliptical pupils
