The radiated ratsnake, copperhead rat snake or copper-headed trinket snake (Coelognathus radiatus) is a nonvenomous species of colubrid snake.
These snakes are generally very defensive. They are very confident in their ability to defend themselves so you must be very confident in order to remotely have a chance at controlling this species. They are also a good trainer snakes for those looking to get into cobras and other elapids.
