It was a narrative that pulled on the heartstrings. In 2018, an orca known as Tahlequah was seen dragging the corpse of her new child child calf for 17 days, over 1,000 miles alongside the coast of North America. Ultimately, Talequah let the infant go (fortunately, she’s had one other child since), however her behaviour left behind numerous questions amongst scientists about grief in animals.
Different animal behaviour suggests a posh relationship with demise. A mom chimpanzee was noticed cleansing the tooth of her lifeless son. And a few elephant calves have additionally been discovered buried in ways in which counsel grief and mourning.
On this week’s episode of The Dialog Weekly podcast, we converse to Susana Monsó, a thinker who researches animal ethics and animal minds, concerning the other ways animals perceive demise.
Since beginning her analysis on animals and demise, certainly one of Monsó’s favorite animals has been the opposum. These cute, furry marsupials play lifeless after they really feel threatened, as she explains.
“She adopts the bodily and facial expression of a corpse. Her bodily functions are reduced. Her breathing and heart rate drop. Her body temperature drops. She opens her mouth and her tongue hangs out and adopts this bluish hue and she expels this putrid smell and liquid from her anal glands, and she stops responding to the world.”
Monsó, who’s an affiliate professor of philosophy on the Nationwide Distance Schooling College in Madrid, Spain, discovered the opposum’s behaviour so fascinating that the animal grew to become the protagonist of her new e-book, Enjoying Possum: How Animals Perceive Demise.

She says that an opposum’s demise show, which is geared toward convincing a predator that it’s lifeless to present it an opportunity to flee, should have had an evolutionary benefit. However, for taking part in lifeless to work, Monsó says, the predator actually must imagine it.
“The opossum shows us how her predators think of death, what they think a corpse looks like and smells like and feels. That’s why she succeeds in deceiving them, and this makes it more likely for her to pass on her genes.”
However some animals appear to react to demise in ways in which look like counterproductive. Monsó offers the instance of a chimpanzee in a zoo in Valencia that was seen holding onto her child’s corpse for seven months, and to the orca Tahlequah.
“It seems like very maladaptive in a lot of respects … why are these mothers spending so much energy on these babies who are dead, they’re not contributing to passing on their genes.”
Whereas there could also be quite a lot of elements concerned, Monsó says one of many largest is maternal grief and the bond between mom and child.
“These are animals that have extended periods of maternal care and a high level of dependency on the part of the baby. And so evolution needs to have provided the mothers with very strong motivations to take care of the babies because otherwise the babies are not going to make it to maturity.”
Monsó factors to what she calls the minimal idea of demise: one animal understanding {that a} lifeless animal is each now not functioning as it could when it was alive, and that that is an irreversible scenario. She says that some animals might also perceive that demise can occur to people who at the moment are alive, however that it will rely on an animal’s expertise and its intelligence.
