"When animals die, their corpses exude a particular "stench of death"
which repels their living relatives, scientists have discovered.
Corpses of animals as distantly related as insects and crustaceans all
produce the same stench, caused by a blend of simple fatty acids.
The smell helps living animals avoid others that have succumbed to
disease or places where predators lurk. "
Simple explanation.
