$\implies$cockroach

A cockroach can live more than a week without its head before it starves to death. A cockroach could live a relatively long time without its head; some sources said a week, others as long as a month. There are two effects to a surviving headless cockroach.

Answer 2

Headless roaches are capable of living for weeks. To understand why cockroaches—and many other insects—can survive decapitation, it helps to understand why humans cannot, explains physiologist and biochemist Joseph Kunkel at the University of Massachusetts Amherst, who studies cockroach development.
