Cockroaches! Eew! We really hate those filthy insects, don’t we? Damn! They are so disgusting and of course, responsible for spreading diseases. We just hate them! However, we barely know enough about these filthy little insects which often end up infesting our homes. So, in this article on cockroach facts, let us learn 30 interesting facts about cockroaches. We are darn sure that your jaws will drop!
Scientific name: Blattaria
Mind Blowing Cockroach Facts: 1-10
1. There are around 4,600 species of cockroaches. But fortunately, only 30 species share the human habitat. Out of 30 only four of them are quite famous as pests.
2. Cockroaches are highly adaptive and that is the reason why they have been living on this earth way older than us, in fact older than dinosaurs too! If new studies were to be believed, then they evolved 359 million years ago, in Carboniferous period.
3. Are you scared of cockroaches which are of roughly 1 to 2 inches? Then you better don’t see other species of cockroach because they can be as big as 3 inches. The largest cockroach is Megaloblatta longipennis which measures “just” 3.8 inches with 8-inch wingspan. It is found in Central and South America.
4. Another reason why they are so adaptable – they can survive on anything. They can eat debris, fruits, meat, other insects, our food, the list just goes on… they can eat anything just to make sure they live.
5. They are cold blooded animals. This means that they can maintain a low rate of metabolism and hence, can survive without food even for a month. But they can’t stay thirsty. Most cockroaches die of thirst and in general cockroaches can stay without water for a maximum period of about 2 weeks.
6. Guess what? They can live for around a week without their heads. But they can hold their breath for about 40 minutes and they can remain in water for a nice 30 minutes.
7. How do the cockroaches survive without head? After the head of a cockroach is cut off, clotting will seal off the neck and prevent blood loss. The brain of a cockroach is not responsible for breathing and neither is the blood responsible for carrying oxygen throughout the body.
8. The cockroaches have something called spiracles. These are little holes in their bodies which are present in almost every segment of the body. The spiracle pipes are responsible for sending air directly to the tissues using tubes which are known as the tracheae.
9. In addition to that, they have ganglia clumps that are present within each segment of the body. These ganglia clumps are nothing but agglomerations of nerve tissues, which are very much capable of performing the basic nervous functions which control the reflexes.
10. So, a cockroach can survive decapitation. However, it will eventually die off because of thirst and hunger (thirst will kill it first because they can’t stay thirsty for a very long time).
