Opossums are unique animals with fascinating survival strategies, including "playing dead." This instinctual behavior, known as thanatosis, allows them to deter predators by appearing lifeless. However, this tactic can make it challenging to determine whether an opossum is truly dead or simply pretending.
This guide will cover the telltale signs to distinguish a lifeless opossum from one employing its natural defense mechanism. Understanding these signs is essential for homeowners, wildlife enthusiasts, or anyone encountering a distressed opossum.
Thanatosis is a survival mechanism used by opossums to avoid predation. When threatened, they fall to the ground, become limp, and exhibit behaviors mimicking death. Depending on the perceived danger, this state can last several minutes to a few hours.
Breathing is the most reliable indicator of life. Even when playing dead, an opossum continues to breathe, although it may be shallow and slow. Look closely at the chest or abdomen for subtle rising and falling movements.
Rigor mortis, the stiffening of muscles after death, begins within a few hours of an animal’s passing. An opossum playing dead will remain limp, while a truly dead opossum will have stiffened limbs.
When an opossum plays dead, its eyes may remain open, but it will not react to light or touch. Shine a flashlight into the eyes to see if the pupils contract or dilate. A lack of reaction could indicate death.
A living opossum maintains a warm body temperature, while a dead one gradually cools to match its surroundings. Carefully touch the body to feel for warmth, focusing on areas like the underbelly or armpits.
An opossum playing dead will eventually "revive" once it perceives the danger has passed. This could take anywhere from a few minutes to a few hours. Watch from a safe distance to see if it begins moving or changes its position.
Severe injuries, bleeding, or visible wounds could indicate the opossum is not just playing dead but has suffered fatal damage. However, opossums are resilient and can survive injuries that might appear fatal at first glance.
If you suspect the opossum is playing dead, leave it undisturbed. Back away slowly and ensure the area is quiet and free from threats. The opossum will typically regain consciousness and leave once it feels safe.
Handling an opossum can cause stress and may lead to defensive behaviors, such as hissing or biting. Only attempt to move the animal if it is in immediate danger, such as lying in a roadway.
Observe the opossum for signs of revival. If it does not move after several hours or appears distressed, consider contacting a wildlife professional for guidance.
If you’ve determined that the opossum is dead, proper disposal is necessary to prevent health risks and deter other wildlife.
Double-check for breathing, rigor mortis, and unresponsiveness to ensure the opossum is dead before proceeding with disposal.
Follow local regulations for animal disposal. This may involve:
Clean and disinfect the area where the opossum was found, especially if it was on your property. This helps prevent the spread of disease and removes lingering odors that might attract other animals.
If you’re unsure whether the opossum is alive or dead or in a hazardous location, contacting a wildlife professional is the safest option. Professionals have the tools and expertise to handle wildlife humanely and effectively.
False. Thanatosis is an involuntary response triggered by extreme fear, not a conscious decision by the opossum.
False. While seemingly lifeless, a startled opossum may lash out if handled, so caution is always advised.
Determining whether an opossum is truly dead or just playing dead can be challenging, but it is crucial for handling the situation appropriately. You can confidently assess the opossum's state by observing key indicators like breathing, body temperature, and responsiveness. If in doubt, give the animal space and contact a wildlife expert.

Opossums are fascinating creatures with unique survival tactics, including their well-known ability to "play dead." Encountering an opossum, whether injured or seemingly lifeless, can raise many questions about how to handle the situation. This FAQ section answers common queries about identifying whether an opossum is dead, what to do with an injured one, and understanding their defense mechanisms like thanatosis, offering guidance for safe and humane actions.
Look for signs of breathing, subtle movements, or warmth in the body. Opossums playing dead will remain limp and unresponsive but will eventually recover when they feel safe.
If an injured opossum is in a hazardous spot, carefully move it using gloves and place it in a safe, quiet area. For further assistance, contact a wildlife professional or local rehabilitation center.
The scientific term for this behavior is thanatosis, an involuntary response triggered by extreme fear, mimicking death to discourage potential threats.
Opossums in thanatosis may appear lifeless for extended periods as their bodies go into a temporary state of paralysis, complete with a limp body and odor secretion to enhance the illusion.
A truly dead opossum will have a cold body, while one playing dead will retain warmth, particularly in the underbelly or armpits. Use gloves to check safely.
Place the injured opossum in a ventilated container lined with a soft cloth in a dark, quiet area. Avoid offering food or water and contact wildlife rescue immediately.
If the opossum’s pupils are unresponsive to light and the eyes appear glazed or sunken, it may be dead. However, if the eyes are open but not moving, it could be playing dead.
