Shell Armor - Biomimicry Composites

Here is a new study on a deep water sea snail who has an amazing shell. It lives by geothermal vents so it experiences extreme fluctuations in temperature and acidity. Yet in this highly corrosive environment this snail shell still provides protection from predators.

It is no surprise that researchers are looking at this type of shell to provide insights for new armor. Biomimicry is one of my favorite topics here as there is much we can learn from mother nature. She has after all been inventing and modifying for millions of years.

What other "animal armor" is out there that perhaps we should look at? Take the desert tortoise for example, much like a Humvee in Afghanistan the tortoise's armor needs to be lightweight, strong, and withstand the harsh environments.
