No, I Called You a Skink!
The sand skink, Plestiodon reynoldsi, is famous for its ability to swim through sand at depths of up to 10 centimetres. That’s strange because although sand sometimes act like a fluid, it also acts as a solid supporting large loads such as human footfall. So how do sand skinks do it?
