    Cockroaches, along with some other insects, can survive for weeks after suffering decapitation. The cockroach’s circulatory system is an open system. Remove the head and the cockroach’s neck will often seal off the wound by clotting, thus preventing uncontrolled bleeding. The roach’s brain has no control over its breathing, and the blood of the cockroach doesn’t carry oxygen. When a decapitated cockroach dies, it is usually the result of starvation. Without a head, it cannot eat. Source: ScientificAmerican.com
