I went looking for a credible source and the first one I found was paywalled. Found https://www.berrypatchfarms.net/do-snakes-take-fall-damage/ which links some credible sources. If you choose to trust it (site looks make me want to say no but the information feels okay??)…

According to researchers, these natural “shock absorbers” are why the internal organs of snakes remain unharmed even after high falls (3). One analysis found that snakes landed with an impact force up to 7 times their body weight from falls over 10 feet, yet did not suffer any organ damage (4).
