1.) A Cockroach Can Live for Week Without Its Head
Due to their open circulatory system, and the fact that they breathe through little holes in each of their body segments, they are not dependent on the mouth or head to breathe. The roach only dies because without a mouth, it can't drink water and dies of thirst.
2.) A Cockroach Can Hold Its Breath for 40 Minutes
These pests can even survive being submerged under water for half an hour. They hold their breath often to help regulate their loss of water.
3.) They Can Run Up to Three Miles in an Hour
While this may seem like an impressive athletic ability, what it really means is that they can spread germs and bacteria throughout a home very quickly.
