What is rigor mortis and how would the onset of rigor mortis differ depending on the kind of neurotoxin the animals were exposed to?

Rigor mortis (literally "stiffness of death") is a natural process within the body after somatic death in which the skeletal muscles become locked in a contracted position. The carcass becomes rigid and unbending. Intoxication with a neurotoxin could affect the development of rigor mortis. For instance, tetanus toxin would cause the animal to be practically in rigor mortis at the time of death because it causes a spastic paralysis where the muscles are contracted during life. In contrast, botulinum toxin might cause the animal to have delayed rigor mortis or even to not develop a full rigor mortis because it blocks the nerves and causes a flaccid paralysis.

Rigor mortis results from what?

Rigor Mortis, which is Latin for "stiffness of death" is one of the recognizable signs of death. It is caused by chemical changes in the muscles after death, causing the limbs of the corpse to become stiff and difficult to manipulate. Generally, in average temperatures, Rigor Mortis begins after approximately three to four hours and reaches maximum stiffness after 12 hours. Following this it begins to dissipate until approximately 48 to 60 hours after death.
