There is a breed of gerbil, common around the southern parts of Africa who have the most interesting evolved defense mechanisms. This species of gerbil has teeth that have evolved to be so durable that in the winter they have been seen to burrow straight into the sides of trees, or through wooden walls of houses to escape the cold and predators. They do this primarily from them using the top two teeth like a can opener, the using their strength to pull backwards allowing chunks of wood to be dislodged
The day the Missles hit changed everything. On the 42nd of Menae, it was a pretty normal day. I was in school when it happened. One minute we were mixing chemstat solutions, and the next we were all watching the feed.
Luckily we were not there, but students and teachers alike stood in shock as massive Cylinders fell from the skies onto the local transit centers. Upon hitting the ground these Metalic tubes created the biggest explosions I had ever seen.
This was our first contact, this was the day we met the “hoo-mens”
