The flying snake has venom, but much like garter snakes, the snake is so small that the amount of toxins in their saliva is only enough to kill their prey, which will be covered later on in the section about the flying snake's diet. If challenged by an animal far bigger than their venom can bring down, they might bite anyway just to give the predator a great deal of pain, or may choose "flight" rather than "fight" and "fly" away.
