I once read an article about a forensics lab, if memory serves, its in Georgia. They study the decomposition of corpses using dead pigs as a substitute for humans.
According to one of the researchers, larva of some species or other will move in unison if the corpse is disturbed by some other animal. The speculation was that the thousands of maggots will, at some signal, all move together, causing the corpse to jerk or move and thereby scaring off a potential thief of their meal.
Wet squishy science was never my thing but insect behavior does interest me. The ability of many small, disconnected systems with limited function achieving a grander but unaknowledged task fascinates me. Has anyone heard of this phenomena? or did I fall asleep reading Steven King.
