While I didn't see it specifically mentioned, it sounds like it might help eliminate the need for special "stab protection" in law enforcement body arnor, besides making it more flexible.

Also, I wonder if it could be used for other types of protection, such as an outer layer of blast protection.

The animal rights people would not allow fish to be used in such an experiment. Pete

Okay, but I'm still waiting to see the Arapaima on River Monsters.

Chuck, sorry to disappoint you. It would have been a lot more dramatic, that's for sure. I'd guess that the reason a real piranha was not used in the experiment was most likely because of the danger and hassle involved with handling a real piranha. I wouldn't want to tangle with one of those, even if sedated.

This particular one you've covered is very impressive. Just the fact they could identify the Amazonian Arapaima gigas fish as having the qualities they needed for their sythetic material is brilliant.

In some ways, we look to nature because -- well, where else are you going to look. In recent years, however, I've seen there is a more deliberate look to nature for innovation. This is even true in the pharma industry. They're looking to nature for medicinal drugs. For one thing, drugs occurring in nature don't have to go through the same multi-year qualification process.

Current military body armor uses a kevlar layer and a ceramic plate to provide protection against high powered rifle bullets.  The kevlar is a woven fabric built up in layers at angles.  The ceramic plate is added to provide protection from rifle bullets.  Seems like that part of the armor is already being used.  The overlapping scale idea is interesting.  This might hold promise for lighter, stronger armor.

Joel, it's actually both. The scales' flexibility is important for multiple reasons, according to the original study, which stated that the corrugated surface helps enable the flexibility of the outer layer of scales, which in turn leads to the difficulty of penetration by piranha teeth.
