Very interesting, secondary adaptation of a trait.

Here I thought it was so they would never feel homeless
Right! They are so very "attached" to their shells - unlike hermit crabs who change theirs as they grow out of it.

Still not sure.
We'll need a bit more yet.
Protection from predators from underneath still sounds plausible tp me.
wait until next year.

I thought it was because predators like them crunchy when they eat them, kinda like chips

It's just their evolution and the reasons may now be lost in time and space.

So as to protect themselves. :rolleyes: These cute little animals are so slow, they cannot fly, their shells - I believe - do protect them. ;)

Can you guys imagine turtles walking around with no shells in 2050 XD
Get a sneak preview of them in one of the worst movies ever: Laserblast. Only saw it because it was on an episode of MST3K. XD

How can these not be torts without shells?!
