Cockroaches have a decentralized nervous system, meaning they do not rely on their brains for basic bodily functions.

Their bodies are equipped with ganglia—nerve tissue clusters—that control movement and reflexes independently of the brain.

Since cockroaches breathe through spiracles (tiny openings on the sides of their bodies) and not through their mouths or heads, decapitation doesn't immediately affect respiration.

Additionally, cockroaches have open circulatory systems and low metabolic rates, which allow them to survive for several days without a head.

However, they eventually die due to lack of water intake, as they can no longer drink without a mouth.

Studies have shown they may survive anywhere from a few days to over a week, depending on environmental conditions like temperature and humidity.

This bizarre survival trait has made cockroaches an iconic example in biology discussions about insect resilience and distributed neural systems.
