From the fearful account of Leviathan described by God in Job 41, we learn that this creature’s body armour is resilient indeed. “Though the sword reaches him, it does not avail, nor the spear, the dart, or the javelin.” (v. 26; similarly vv. 7, 13, 28–29)Hopefully, you're flexible enough to read the rest of the article.

There are creatures familiar to us today that are also wonderfully protected by resilient (yet flexible) body armour—e.g. the scaled skin of fish and pangolins, and the osteoderms (bony plates embedded in the skin) of armadillos and crocodiles. Perhaps these creatures give us an insight into the leviathan’s body armour? The crocodile’s exterior in particular is renowned for being highly resistant to puncture, able to resist arrows and even bullets. No wonder then that scientists and engineers have been avidly studying such natural armour as a guide to designing flexible protective coatings for industrial applications, personal body armour, and flexible electronics.
