The Journal of Zoology Studies reported that some snakes can fly from a tree to an other tree. Here you can see a picture: http://www.khatarnaknews.com/wonder-flying-snake-near-at-coimbatore-in-tamil-nadu/
Not only that, but in Japanese the difference between fly and (an airborne?) jump is only in writing (they'll say the equivalent of 하늘을 납니다 = "leap/fly the sky" and such to be clear), and according to https://marisha39.com/w/nalda/ 날다 means both. The vipers here and in Korea, 살무사 (they're distinguished by their triangular heads), unlike most vipers in the world, can jump.
