Flies can still function even when decapitated

I found an interesting clip of a decapitated fly which could still function, which was new to me. An insect’s body is controlled by many ‘segmental ganglia’ in the abdomen and thorax, as opposed to it being entirely controlled by the brain. This means a fly or other similar invertebrate could live entirely without a head until it eventually died of starvation.

My dad backhanded a fly and it’s head fell off. from WTF
