Survival Mechanisms of Cockroaches

When a cockroach loses its head, it doesn't die immediately. The wound seals quickly, allowing it to survive without a brain due to nerve clusters that manage basic functions. Cockroaches breathe through body holes, not needing a nose. Eventually, they die from dehydration as they can't drink without a mouth.
