How Does a Cockroach Live Without Its Head?
WouterMany people are curious about how a cockroach survives without its head, but do you know that it can live without it for a year or more? These critters are among the most resilient insects known to man. In fact, they can survive exposure to radiation, as well as decapitation.
Cockroaches are able to function without their heads because their bodies are equipped with nerve tissue. These nerve tissues control the movement of each segment of the body and perform reflexes. These nerve tissues help the cockroach stand up, move around, and react to touch. In addition, cockroaches don’t need much food compared to humans.
Cockroaches’ vascular system is similar to our own, but without small capillaries. Because of this, they are able to circulate blood at a low pressure. This means that bleeding will be very slow, and there is no danger of uncontrolled bleeding. Because cockroaches breathe through spiracles, their blood is able to clot at the decapitation site, which is another reason why they can survive if their head is removed.
Because they don’t have a head, a cockroach that loses its head won’t die of starvation. They can still find food and water, but without its head, they won’t be able to eat it. They will die in a week or so, but without its head, it still poses a risk.
