cockroach

I'm not nuts about them either, but they are fascinating animals. Consider:

Six legs with eighteen knees, they can hold their breath for 40 mins or stop their hearts at will, can run up to 6 km/h (3.25 mph) and can survive a week after being decapitated (it can't drink water, so it dies of thirst).

The bad news is that some female cockroaches mate only once, and are pregnant the rest of their lives. Whatta bummer.
