Did you know insects can live without their heads? We take a look at how long a cockroach could survive without its head <\/p>
The insect nervous system is based on nerve nodules (ganglia) repeated in each body segment. While the \u2018brain\u2019 ganglion in the head is important, it is not the vital, all-controlling organ we see in vertebrates.\u00a0<\/p>
They also have an open circulatory system<\/a>, rather than a network of blood<\/a> vessels, and breathe through spiracles, or little holes in each body segment. So in theory it is possible for insects to live without their heads.<\/p> \u00a0The cockroach\u2019s brain does not control\u00a0its\u00a0breathing\u00a0and blood does not pump oxygen to the body. Instead,\u00a0air\u00a0is piped\u00a0directly to tissues through a set of tubes called tracheae.<\/p> Deprived of its head,\u00a0the\u00a0cockroach can therefore survive for hours or even days with little or no change to body function, breathing or metabolism.<\/p> \u00a0It\u00a0continues to\u00a0function in terms of simple reactions.\u00a0However, without its head the cockroach will be unable to eat, and so will eventually starve to death\u00a0\u2013\u00a0though\u00a0they can survive for weeks on one meal so\u00a0this\u00a0may\u00a0take\u00a0some time.<\/p> \u00a0Equally, the cockroach\u2019s head can survive without its body, moving its parts for\u00a0several\u00a0hours.<\/p> Also one note – don’t try your own experiment <\/p> Discover more fascinating insect facts<\/strong><\/p> Did you know insects can live without their heads?
