What Animals Play Dead

The leaf litter frog (Ischnocnema aff. henselii) was recently spotted acting out an exaggerated death. It joins a long list of animals that play possum.

Anyone planning a fright for Halloween might learn a trick from a South American frog that dramatically fakes its own death, according to scientists.

Leaf litter frogs (Ischnocnema aff. henselii) of southern Brazil were recently observed playing dead by turning belly-up, shutting their eyes, and throwing back their arms and legs. The frogs stayed in their exaggerated death pose for about two minutes, according to a team lead by biologist Vinicius Batista of the State University of Maringá in Brazil and reported in the fall issue of the Herpetological Bulletin.

The behavior has not been seen before in this species, and it’s more dramatic than scientists are used to seeing in other animals. But it’s not uncommon for frogs to play dead in some way, says Andrew Gray, curator of herpetology at the Manchester Museum, U.K.

Technically known as thanatosis, playing dead is a way to trick predators that watch for movement in potential prey. And as the nickname “playing possum” suggests, it’s not unique to frogs.

Fire-bellied toads from Asia and Europe also get dramatic in fake death. When playing dead, the toads (which are scientifically classified as frogs) arch their backs and contort their limbs to display yellow or orange warning markings on the undersides of their feet. They may also flip onto their backs to show similar markings on their underside (hence the name fire-bellied toad).

Playing Dead Is, In Fact, Not An Act For Possums

It’s thought that the lack of movement caused by thanatosis may focus a predator’s attention on such warning markings, or on foul-smelling odors.

When it plays dead, this fire-bellied toad rolls over to show the markings on its underside—an indication it has toxins in its skin.

The American opossum (Didelphis virginiana) and hognose snakes from the North American genus Heterodonare two types of death-fakers that employ scents in their acts.

The opossum also assaults a potential predator’s olfactory while playing dead. Dead animals may harbor dangerous bacteria and other harmful organisms, so many predators instinctively avoid eating them.

Among invertebrates such as ants, beetles and other insects, death-feigning is a fairly common survival tactic, but there’s also a spider that uses the behavior for sex.

Faking It! Animals That Play Dead And Why They Do It

During courtship, the male nursery web spider (Pisaura mirabilis) offers the female a silk-wrapped insect. If the larger female attempts to steal the food without mating, the male plays dead and is dragged off along with his gift.

“It seems as if death-feigning and hanging on to the gift allows him to stay close to the female, ” says Trine Bilde, an evolutionary ecologist at Aarhus University in Denmark.

Bilde, who was the first scientist to record the behavior, says the nursery web spider is the only known animal that plays dead to induce mating.

Some preying mantid males freeze when trying to get away from cannibalistic females after mating, “but not to achieve mating, ” Bilde notes. “So that would be an anti-predator behaviour.”

There are also predators that play possum. Two species of cichlid fish are known to pretend to be dying or dead to attract scavenging species as prey.

Lurking in Lake Malawi in East Africa, Livingston’s cichlid (Nimbochromis livingstonii) has been observed sinking to the bottom of the lake and lying motionless on its side, waiting for a moment to strike.

These marsupials used to exist only in the southern United States. But lately they’ve been showing up in Canada too. They’ve been spotted in British Columbia, Quebec and Ontario. But they’re no safer here than they are in the U.S. They’ve still got plenty of predators here, like owls, foxes, eagles and even dogs and cats.

So how do they make a getaway when a predator is lurking around? They flop on the ground and pretend to be dead. Sometimes that alone will stop a predator from chowing down on them straight away. But Opossums go one step further to protect themselves by releasing a nasty odour. It smells like the Opossum has been dead for

Not all animals play dead to avoid being eaten. Some play dead … for mating purposes. Female Nursery Web Spiders usually make males jump through hoops before they mate with them.

Males shower females with lovely gifts like silk-wrapped insects. But that doesn’t always impress females — sometimes the females will try to grab the insect and run! However, these males are rather clever. They play dead and let themselves be dragged along with the silk-wrapped insect. Then they wait for the female to start to eat before they “come alive” again reading and willing to mate with the female!

Eastern Hog-Nosed Snake populations have been dropping for years now. This snake has even been listed as Threatened in Canada under the

The Power Of Playing Dead

Many animals prey on this snake, from bigger snakes to coyotes, skunks, weasels, eagles, wild turkeys, cats and dogs. But this brave snake has a few tricks up its sleeve to get out of trouble. First, it rears backward and hisses at the predator. It may even strike out. But if the predator keeps attacking, the snake will drop to the ground and play dead. It rolls onto its back with its tongue sticking out and might even defecate!

Like this cricket, this is also the fate for many grasshoppers. In response, the grasshopper’s body becomes stiff, and its limbs will stick out in all sorts of awkward positions.

When a frog gets its hands on a grasshopper, the grasshopper pretends to be dead. Its body becomes stiff, and its limbs will stick out in all sorts of awkward positions, making it hard for a frog to swallow the grasshopper. This buys the grasshopper a bit of time to escape the frog’s clutches!

Playing Possum: 9 Animals That Play Dead To Survive

Black Widows get a bad rap when in reality, they are actually kind of shy! If they’re threatened, they usually run away as quick as their eight legs can carry them. They might also throw silk at a predator (it’s actually called silk flicking!).

They play dead in the hopes that will stop predators from hurting them. Black Widows bite only if they don’t feel like they have much of a choice.

When she’s not writing for CWF, you’ll probably find her playing with her daughter Nora.is a behavior in which animals take on the appearance of being dead. It is an immobile state most oft triggered by a predatory attack and can be found in a wide range of animals from insects and crustaceans to mammals, birds, reptiles, amphibians, and fish.

The Biology Of Death Feigning

Appart death is a form of animal deception considered to be an anti-predator strategy, but it can also be used as a form of aggressive mimicry. Wh induced by humans, the state is sometimes colloquially known as animal hypnosis. The earliest writt record of animal hypnosis dates back to the year 1646 in a report by Athanasius Kircher, in which he subdued chicks.

Tonic immobility (also known as the act of feigning death, or exhibiting thanatosis) is a behaviour in which some animals become appartly temporarily paralysed and unresponsive to external stimuli. Tonic immobility is most gerally considered to be an anti-predator behavior because it occurs most oft in response to an extreme threat such as being captured by a (perceived) predator. Some animals use it to attract prey or facilitate reproduction. For example, in sharks exhibiting the behaviour, some scitists relate it to mating, arguing that biting by the male immobilizes the female and thus facilitates mating.

Evidce for this includes the occasional responsive movemt, scanning of the vironmt and animals in tonic immobility oft taking advantage of escape opportunities. Tonic immobility is preferred in the literature because it has neutral connotations compared to 'thanatosis' which has a strong association with death.

A deer in headlights and an opossum playing dead are common examples of an animal freezing and playing dead, respectively. Freezing occurs early during a predator-prey interaction wh the prey detects and idtifies the threat, but the predator has not yet se the prey.

Because freezing occurs before detection and is used to better camouflage the prey and prevt the predator from attacking, it is considered a primary defse mechanism.

Tonic immobility occurs after the predator has detected
