It is known that immersing humans in liquid dramatically improves their resistance to gee forces. Why would it not do so for other species? I'm wondering if some of the answer is simply that the goldfish never evolved to deal with those kinds of shocks, while lizards can indeed fall from trees or off of rocks. | |

In addition, it's completely different than acceleration in spaceflight, because the bowl is getting shaken back and forth. A bowl constantly accelerated in one direction will have no pressure waves propagating through it, as it's identical to a body of water sitting on a planet with a different gravitational acceleration. Finally, the comparison to dynamite fishing is completely meaningless, since the accelerations involved there are many orders of magnitude greater than those encountered in spaceflight. | |

Adding in more detail for the pedants

| Nov 22, 2018 at 0:40 | comment | added | Johnny | I'm skeptical of your claim that the lizard will escape largely unscathed after being slammed against the sides of the fishbowl as it's shaken. If this photo is legit, then this gold fish survived falling 1m to the floor in his fishbowl. The sudden deceleration at the end didn't appear to be fatal. | |

| Nov 21, 2018 at 20:21 | comment | added | ths | your proposes experiment is a bit cheating. you advise us not to try it and i suspect you haven't either. so why should we believe your conclusion? (aka citation needed) | |
