Sun absorption ?

[Mark L]

Does anyone know if tortoises (leopards) get their beneficial sun ray absorption through their carapace or skin or both ??

Skin, shells don't asorb

UVB is definitely through the skin. Heat is through everything.

Skin. Not shell.
This is possibly why a basking tortoise or turtle stretches it's legs right out, front and back, to give maximum surface area for UV absorption.
