Q: Are there poisonous snakes in Rhode Island?
No, we have no venomous snakes. Timber Rattlesnakes (Crotalus horridus) were once found in Rhode Island, but disappeared over thirty years ago. There are still rattlesnake populations in Connecticut and Massachusetts. Copperheads (Agkistrodon contortrix) are also found in southern New England but have never occurred in Rhode Island. Lastly, although there are many stories about water moccasins in Rhode Island, these tales obviously refer to common Water Snakes, because the real water moccasin, or cottonmouth as it is sometimes known (Agkistrodon piscivorus), is a southern species found no further north than the state of Virginia.
