Cockroaches are known for their remarkable resilience, able to survive extreme conditions such as high radiation, extreme temperatures, and narrow spaces. One of their most surprising traits is their ability to live for up to a week after losing their heads. This is due to their decentralized nervous system, where clusters of nerve cells called ganglia allow basic functions like movement and reflexes to continue without a brain. Their open circulatory system prevents catastrophic blood loss upon decapitation, and they breathe through tiny openings called spiracles, which deliver oxygen directly to tissues. However, despite these adaptations, a headless cockroach eventually dies from dehydration since it can no longer drink water.
