These are my legs [back] - all work done by Matt W. at Scorpion studio in Houston, Texas.
My right leg bears a pair of Ceolacanths, an ancient species of fish thought to be extinct until 1938.
My left leg wears a pair of saltwater crocodiles.
The ankle band on both legs is a strand of human DNA in two of the more common representations.
There is of course significant detail that isn't viewable in these images.
