Spiders (and other small animals) are in fact fine with falls many times the height of their own body, because of the difference in how quickly volume (and therefore mass) and surface area (and therefore air resistance) are scaling. On the other hand, the larger they are, the harder they fall
I believe you’re referring to Terminal Velocity
Small animals bounce, medium animals break, big animals splash
(FYI, do not look up examples)
A spider can literally float if it farts out some silk.
A horse becomes soup.
Right in theory. But I used to live on the fifth floor and carried spiders to the window like I used to do before. In that Appartement the only difference to before was that I yeeted the spider from a height of 15m and not just 1m. That must be like skydiving without a parachute for the spider.
You could throw that spider off the 50th floor, it would be fine: https://youtu.be/f7KSfjv4Oq0?feature=shared
