Can a Cockroach Survive Without its Head?

Yes, unlike humans cockroaches have a very simple circulatory system, and the blood will just clot, and not spew all over the place like humans, and not die.  They can breathe through holes in each body segment called spiracles, also unlike humans. They wouldn't starve either, because they can survive for weeks before facing starvation. So roaches can survive up to weeks without their head.- John Baskin
