Octavia, an octopus on the New England Aquarium in Boston, was previous and dying. She had been moved from her show tank to a quieter, darkish place that resembled an octopus’ den. That is the place the animals go to within the wild when they’re nearing the top of their lives.
Her pal, Sy Montgomery, needed to say goodbye.
The creator and naturalist had identified Octavia for a number of years. Montgomery had fed Octavia fish and performed together with her numerous occasions. It was a part of Montgomery’s analysis for her 2015 ebook The Soul of an Octopus. Montgomery describes the animal’s exceptional intelligence. She had befriended 4 octopuses (sure, that is the proper plural) with very totally different personalities.

When DW spoke to Montgomery, she recalled the final time she noticed Octavia.
“She was sick, she was previous and she or he was clearly dying,” Montgomery mentioned. “I opened the tank and she or he floated to the highest to see me. And she or he was not hungry ― I handed her a fish and she or he simply took it and put it apart. She made the hassle to return up from the underside of that tank to see me and to the touch me. She prolonged her suckers to me and regarded me within the face and held me for minutes.”
That was after a interval of 10 months throughout which Octavia had been down in her den, all on her personal. She hadn’t seen Montgomery or different folks. For an animal that solely lives three to 5 years, “10 months is a long time,” Montgomery mentioned.
Quickly after that Octavia handed away.
Feelings — not simply reflex reactions
Their final goodbye was considered one of many interactions that Montgomery has had with octopuses that make her sure they’ve feelings. Her take is predicated on private experiences, anecdotal proof. However Montgomery is not alone in her evaluation.
There’s a consensus within the discipline of animal sentience that octopuses are acutely aware beings — that they will really feel ache and actively attempt to keep away from it.
Kristin Andrews and Frans de Waal posit in a brand new report printed within the journal Science that many animals, together with cephalopods resembling octopuses really feel ache . However they do not simply react reflexively, like a baby pulling away their hand from a scorching range. That sort of response is called nociception.
Octopuses show reactions that go far past that, say Andrews and de Waal, citing analysis from the previous 20 years.
Octopuses can change their shade and mix in with the atmosphere
“Nociception doesn’t essentially attain the central nervous system and consciousness,” they write within the Science article — meaning the animal might need to keep away from ache, however that this ache does not include any related feeling.
Octopuses, nonetheless, have proven that they keep away from locations the place they beforehand skilled unfavorable stimuli, even when they’re freed from ache in that very second.
That, Andrews and de Waal write, is as a result of they keep in mind the ache they felt there, processed it and famous it as one thing they need to keep away from. They really feel a reminiscence of ache.
The distinction between feelings and emotions
When researchers take a look at the inside lives of animals, they distinguish between feelings and emotions.
Feelings, write Andrews and de Waal, are “measurable physiological and/or neural states which are typically mirrored in habits.”
That features elevated physique temperature, elevated neurotransmitter and hormone exercise or an animal’s avoiding a spot the place a scientist poked it with a stick the opposite day.
Emotions, however, occur at a deeper stage than feelings.
Human animals typically share their emotions verbally. We are saying issues like “I am so glad!” or “That makes me actually offended.”
Individuals cannot talk with different animals on that stage. So, it is not possible for us to know precisely what non-human animals really feel. However that does not imply they do not really feel something.
Chatting with DW, Andrews mentioned “scientists ought to settle for the feelings-side of feelings for animals, identical to we do for people. The ‘yay!’ of pleasure, the crushing, heavy despair of unhappiness. Emotions of ache, emotions of enjoyment or of solar in your pores and skin.”
“We won’t measure that in animals. However we won’t measure it in people both,” mentioned Andrews, the Analysis Chair in Animal Minds at York College in Toronto, Canada.
Scuba divers like filmmaker Craig Foster say octopuses are extremely curious creatures
Montgomery makes the identical level. Certain, she does not know what emotions are at play when an octopus comes as much as the water’s floor to the touch her gently. However can we ever have that information about one other residing creature, she asks.
“I do not know what octopuses really feel of their hearts,” Montgomery mentioned. “However I additionally do not know what my husband really feels or whether or not happiness for him feels the identical as happiness feels for me.”
Vital step for animal welfare
The UK has taken a step in the direction of recognizing octopuses and their relations as sentient — as their being acutely aware, with emotions and recollections of ache.
Cephalopod molluscs, like octopuses, and decapod crustaceans, like crabs, lobstersand crayfish, are included in a brand new animal welfare regulation that’s going by way of the UK parliament proper now.
Jonathan Birch, an affiliate professor on the London College of Economics, led a crew that checked out greater than 300 research earlier than advising the UK authorities on the regulation.
If the UK’s new animal welfare regulation is handed, crayfish, octopuses and their relations will take pleasure in greater ranges of safety
“The proof tilted in the direction of the animals being sentient,” Birch mentioned. “We really useful the inclusion of all of those animals within the scope of the animal welfare regulation. However the proof was significantly sturdy for octopuses.”
Birch says it is human to search out it laborious to empathize with animals like crayfish or octopuses, “as a result of they appear so totally different from us and so they appear so alien.”
“However that does not imply there’s nothing there to empathize with, it doesn’t suggest they do not have emotions,” he mentioned. “We have got to be led by the proof on this.”
