Rigor morits takes place mostly because the muscles cannot relax after someone dies. The bones in a person's body start to actually contract within themselves and the skeletal muscles start to do the same.

A few hours after a person dies the joints of the body stiffen and become locked in place. Rigor mortis is caused by the skeletal muscles partially contracting. The muscles are unable to relax, so the joints become locked.

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.
