Approximately 35 species of snakes live in Indiana. Most of them are harmless. Of the four species of venomous snakes that live in the state, only one is both widespread and not endangered. Snakes found in Indiana should be left in the wild, as a state law protects non-game amphibians or reptiles from being collected without a valid license, and the majority of the state's snakes cannot be collected even with the appropriate license.
