Cockroaches… the mere thought of them sends a shiver down most people’s spine. They get into food storage, reproduce at lightning speeds, and are really fast movers. It’s been said that cockroaches will survive Armageddon and anyone who has had to deal with a cockroach infestation wouldn’t doubt that. These critters have been around for millions of years, even outliving the dinosaurs. They are a resilient insect that has adapted to the ever changing environment of the Earth.
Have you ever turned on the kitchen light and seen how fast cockroaches bolt into hiding? Or maybe you tried to hit one with a shoe but it was just too fast for you. Cockroaches can sense currents of air and use this for detecting any threat that is approaching them. It’s been reported that a cockroach can hit the ground running a mere 8 milliseconds from the time they feel a puff of air. They can hit 80 centimeters a second and reach three miles in about an hour. They also have this ability to switch directions at the drop of a hat.
As mentioned earlier, cockroaches have been around for a very long time. There are some cockroach species that can endure freezing cold temperatures. If a cockroach loses its head it can still continue to function for a week. This is because cockroaches have an open circulatory system, meaning they have no veins and their organs are all housed within the body cavity. This also means that they don’t bleed out when wounded.
