Your Armored Reptile

Summary

The Cape Cliff lizard sports a bony body armor.

The Cape Cliff lizard, Hemicordylus capensis, belongs to the family of girdled lizards, which have protective bony plates embedded in their skin. It lives in high-altitude areas throughout South Africa’s Cape Fold mountains. Its agile long legs and digits enable it to scurry across the mountains’ steep rocks, and bone fragments in the skin provide protection. Our hair and skin can be traced back to the scales of ancient, long-extinct reptiles that connect us to this armored lizard.
