What a humourus coincidence that it was in Australia the upside-down walking beetle was found.
Aussies are walking upside-down, not the beetle.

> The beetle seems to do the opposite thing, though. Why is it the opposite? From the description it seems exactly the same.
From the point of view of the beetle, he's not walking upside down. Physical forces attract him to the "ground" (the underside of the water surfaces) and he just walks normally, as if he was affected by gravity instead of buoyancy. The snail is definitely "upside down", for the physical force (gravity) wants to separate her from the "ceiling" on which she clings.
Aha, I get it, interesting point.

#43Yep, aquatic beetles are able to do this, and snails do it all the time. Is a well known fact.
right? I think I saw it myself and I'm not around water that much

#44I vaguely remember there's a science fiction story about an underwater civilization where the buoyant force servers like gravity for us. Since the force points outwards, for that civilization, the planet is "up above" their head and the space is "down below".
