So how does it do that? The answer is simple, they do not breathe through their head like we humans do, instead they breathe through the spiracles which are present in the body segment. A headless female cockroach can even reach maturity without any difficulty because their organs and nervous system are not centralized. However, they will eventually die of starvation, as they do not have a mouth for intake food.
Cockroaches are arthropods that come under the order Blattodea, which is the same order as termites. There are nearly 4500 species of cockroaches on earth, but only 30 are linked to human habitats and only 5 are considered pests. Cockroaches have segmented bodies and breathe through the spiracles present in the segments of their bodies. The spiracles then provide the air to each cell of the cockroach’s body through the tracheae, a set of tubes.
Another interesting fact about cockroaches is that they do not have blood pressure like a human, which means they do not bleed. Being cold-blooded animals, these insects do not need a lot of food to survive, one meal a day would be more than enough for them to survive a whole month.
For all these reasons, some even believe that cockroaches can last for a month without a head, as long as they do not get infected with deadly mould or bacteria.
