Temperature does effect rigor mortis. Low temperatures slow rigor mortis and it is accelerated by high temperatures.
Rigor mortis does not provide an exact time of death, as it will change depending on factors (such as temperature). However, because it generally follows a rough time range it may be somewhat useful. Usually begins 3hrs after death, reaches its maximum after about 12hrs and is not present after 72hrs. Therefore the degree of rigor mortis gives an estimated time of death.

rigor mortis (rĭ`gər môr`tĭs), rigidity of the body that occurs after death. The onset may vary from about 10 min to several hours or more after death, depending on the condition of the body at death and on factors in the atmosphere, particularly temperature. Rigor mortis affects the facial musculature first and then spreads to other parts of the body. It is caused by chemical changes in the muscle tissue. The state of rigor usually lasts about 24 hours or until muscle decomposition takes place by acid formation.
yes it occurs in all living animals not just humans :)

Rigor Mortis Sets In was created in 1972-11.
The duration of Rigor Mortis - radio - is 1800.0 seconds.
Rigor mortis is a build up of released lactic acid. Rigor mortis starts a few hours after you die, and causes your muscles to contract, or shorten, which is their natural state. After about 12 hours Rigor mortis begins to dissipate.

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 can be accelerated in drowning victims due to the cooling effect of water on the body. The cold temperature can cause muscles to contract and stiffen more quickly than in dry conditions.
Short answer; yes.All muscles undergo rigor mortis at some time after death.
That is the correct spelling for "rigor mortis" -- a Latin phrase applied to the stiffening of muscle tissues after death.
Do not commence CPR if signs of rigor mortis or lividity are present.
