Ever since I got my turtle he's always tried to wedge himself into tight spaces. Behing the filter tube, between rocks, under the heater...
But lately he's acquired this "super-turtle" strength. He's been moving big rocks easily five times his size across the tank. He has one now underneath the ramp of his basking spot, make a space just barely big enough for him to fit through.
He repeatedly swims through this space and "scratches" the top of his shell. Almost as if he's really trying to scratch it. Also lately I've noticed what look like air or water bubbles underneath his scutes. My guess is that he's shedding and this is just some instinctive behavior for peeling off scutes. But you guys know best so I thought I'd ask. Thanks!
Oh yeah, do they have feeling in their shells?
