Sentience In Decapod Crustaceans: A General Framework And Review Of The Evidence, Andrew Crump, Heather Browning, Alex Schnell, Charlotte Burn, Jonathan Birch
Sentience In Decapod Crustaceans: A General Framework And Review Of The Evidence, Andrew Crump, Heather Browning, Alex Schnell, Charlotte Burn, Jonathan Birch
Animal Sentience
We outline a framework for evaluating scientific evidence of sentience, focusing on pain experience. It includes eight neural and cognitive-behavioural criteria, with confidence levels for each criterion reflecting the reliability and quality of the evidence. We outline the rationale for each criterion and apply our framework to a controversial sentience candidate: decapod crustaceans. We have either high or very high confidence that true crabs (infraorder Brachyura) satisfy five criteria, amounting to strong evidence of sentience. Moreover, we have high confidence that both anomuran crabs (infraorder Anomura) and astacid lobsters/crayfish (infraorder Astacidea) meet three criteria—substantial evidence of sentience. The case is, …
Legal Recognition Of Animal Sentience: The Case For Cautious Optimism, Jane Kotzmann
Legal Recognition Of Animal Sentience: The Case For Cautious Optimism, Jane Kotzmann
Animal Sentience
Rowan et al.’s target article provides a valuable indication of the work that was required to reach the point where animals are recognised as sentient in various laws. To ensure this work was not in vain, the language of sentience needs to be used as a moral currency to demand further cultural change involving greater human respect for animals.
Revisiting Donald Griffin, Founder Of Cognitive Ethology, Carolyn A. Ristau
Revisiting Donald Griffin, Founder Of Cognitive Ethology, Carolyn A. Ristau
Animal Sentience
Donald Griffin’s writings, beginning with The Question of Animal Awareness (1976), strove to persuade scientists to study the possibility of animal sentience, the basis of Rowan et al.’s efforts to promote animal well-being. Facing great hostility (but also some acceptance) for his ideas, Griffin initially avoided animal welfare advocacy, fearing it would further undermine his efforts to gain recognition of animal sentience. In later years, however, he began to ponder the ethical implications of animal sentience, intending to study wild elephants’ communication and social behavior to better understand their experienced life and apply it to improving conservation methods. As he …
Crustacean Pain, Michael Tye
Crustacean Pain, Michael Tye
Animal Sentience
This commentary discusses the target article’s methodology, the relevance of the claim that crustaceans lack a neocortex to the thesis that they feel pain, and the evaluation of the results of some trade-off experiments done with hermit crabs.
Of Course Crustaceans Are Sentient: But There's More To The Story, Arthur S. Reber, Frantisek Baluska, William B. Miller Jr.
Of Course Crustaceans Are Sentient: But There's More To The Story, Arthur S. Reber, Frantisek Baluska, William B. Miller Jr.
Animal Sentience
We are in basic agreement with Crump et al. that animal welfare, particularly with regard to the experience of pain, is a topic of importance. However, we come to the issue from a different perspective, one in which all species are sentient and can feel pain. The implications of this theory are discussed.
No Need For Certainty In Animal Sentience, Yew Kwang Ng
No Need For Certainty In Animal Sentience, Yew Kwang Ng
Animal Sentience
This commentary supports Crump et al.’s (2022) point that where risks to welfare are severe, strong evidence of sentience is sufficient to warrant protecting welfare. Crump et al.’s eight criteria for sentience are also useful. Flexible decision-making (5) and flexible behaviour (6) are consistent with Ng (1995). The concession that the “no-need-for-sentience” proposition is unnecessary also strengthens the importance of the target article’s conclusions.
Overcoming Inertia To Deliver Sentience Policy Commensurate With Sentience Science, Claire Bass
Overcoming Inertia To Deliver Sentience Policy Commensurate With Sentience Science, Claire Bass
Animal Sentience
Rowan et al’s target article makes clear that meaningful change in policy and practice to protect animals has failed to progress in lockstep with scientific understanding of their sentience and needs. The underlying causes for inertia in political and practical progress for animals in the UK context are multi-faceted and complex, including economic forces; lack of cross-departmental accountability for animal welfare; and challenges where it suits conservation scientists to dismiss or downgrade the impacts of management decisions on individual animals. All of these influences and more must be understood and addressed if we are to deliver meaningful and timely protections …
Wild Animal Welfare, Clare Palmer, Peter Sandøe
Wild Animal Welfare, Clare Palmer, Peter Sandøe
Animal Sentience
Rowan et al’s article provides an overview of developments in the science of animal sentience and its links to animal welfare policy, especially regarding farm animals. But changing ideas of animal sentience and welfare are also important for managing wild and other free-living animals. We ask how the welfare of these animals differs from that of farmed animals, especially how the ability to make autonomous choices may matter. We suggest that more research into wild animal welfare is needed to make informed policy decisions, for example, about using animals in rewilding projects and choosing between policies of culling and fertility …
Sentience And Sentient Minds, John Anthony Webster
Sentience And Sentient Minds, John Anthony Webster
Animal Sentience
My commentary builds on Rowan et al.’s (2022) comprehensive review to address the question ‘what do we mean by sentience?’ It suggests how we might recognise degrees of sentience within the animal kingdom, ranging from primitive sensations such as hunger and pain to more complex emotions that determine quality of life.
Brain Complexity, Sentience And Welfare, Donald M. Broom
Brain Complexity, Sentience And Welfare, Donald M. Broom
Animal Sentience
Neither sentience nor moral standing is confined to animals with large or human-like brains. Invertebrates deserve moral consideration. Definition of terms clarifies the relationship between sentience and welfare. All animals have welfare but humans give more protection to sentient animals. Humans should be less human-centred.
Invertebrate Welfare In The Wild, Asher Soryl
Invertebrate Welfare In The Wild, Asher Soryl
Animal Sentience
Mikhalevich & Powell argue that certain cognitive-affective biases might distort people’s consideration of invertebrate minds and that the moral risks of false negatives in sentience research deserve greater consideration under precautionary frameworks. In this commentary, I draw comparisons between biases that concern wild animals and conditions in nature, arguing that the moral risks of disregarding the possible mental welfare of invertebrates are compounded by facts about their lives in the wild.
Global Risks Of Intensive Animal Farming And The Wildlife Trade, Deborah Cao
Global Risks Of Intensive Animal Farming And The Wildlife Trade, Deborah Cao
Animal Sentience
This commentary discusses two issues highlighted by Wiebers & Feigin in the context of the current and future global health crisis: the wildlife trade and factory farming. Both are instances of globalized animal cruelty – in China as well as worldwide -- that require global solutions for the well-being of both humans and nonhumans.
Asian Elephant Rescue, Rehabilitation And Rewilding, Liv Baker, Rebecca Winkler
Asian Elephant Rescue, Rehabilitation And Rewilding, Liv Baker, Rebecca Winkler
Animal Sentience
Thailand has fewer than 10,000 elephants left. More of them are living in captivity to serve the tourist industry under grim conditions than are living free in what is left of their wild habitat. Conservation efforts need to be focused on all surviving members of the species, captive and free, but they need to take into account the inextricable entanglement of human and nonhuman animal lives in Thailand today. There is an opportunity for rescuing, rehabilitating and reintroducing captive elephants to the wild with the help of the traditional expertise of a mahout culture that has been elephant-keeping for centuries. …
Cognitive Relatives Yet Moral Strangers?, Judith Benz-Scharzberg, Andrew Knight
Cognitive Relatives Yet Moral Strangers?, Judith Benz-Scharzberg, Andrew Knight
Andrew Knight, PhD
This article provides an empirically based, interdisciplinary approach to the following two questions: Do animals possess behavioral and cognitive characteristics such as culture, language, and a theory of mind? And if so, what are the implications, when long-standing criteria used to justify differences in moral consideration between humans and animals are no longer considered indisputable? One basic implication is that the psychological needs of captive animals should be adequately catered for. However, for species such as great apes and dolphins with whom we share major characteristics of personhood, welfare considerations alone may not suffice, and consideration of basic rights may …
Yes, Sheep Are Smart But The Moral Question Is Still “Can They Suffer?”, Clare Palmer, Peter Sandøe
Yes, Sheep Are Smart But The Moral Question Is Still “Can They Suffer?”, Clare Palmer, Peter Sandøe
Animal Sentience
Sheep may be more complex and intelligent than we traditionally believed, but knowing this is unlikely to change human attitudes to sheep significantly; nor is it strongly relevant to their moral status. However, knowing more about what sheep are like could help to improve sheep welfare.
Applied Cognition Research To Improve Sheep Welfare, Kristina Horback
Applied Cognition Research To Improve Sheep Welfare, Kristina Horback
Animal Sentience
If a change is going to occur in the care and management of domestic sheep, there needs to be a collaborative effort across many disciplines. This review by Marino & Merskin of the literature on cognitive processing in domestic sheep is limited by the inherent bias of the authors, including the impracticable goal of eliminating sheep production. Animal welfare concerns about the management of commercial sheep are valid; however, in order to make a difference, we need to develop an application for this knowledge about cognitive abilities in sheep.
Cephalopods Are Best Candidates For Invertebrate Consciousness, Jennifer A. Mather, Claudio Carere
Cephalopods Are Best Candidates For Invertebrate Consciousness, Jennifer A. Mather, Claudio Carere
Jennifer Mather, PhD
Insects might have been the first invertebrates to evolve sentience, but cephalopods were the first invertebrates to gain scientific recognition for it.
Using Anthropocentrism To The Benefit Of Other Species, Vanessa Wilson
Using Anthropocentrism To The Benefit Of Other Species, Vanessa Wilson
Animal Sentience
Chapman & Huffman (2018) argue that we should not consider humans as unique or superior to other animals when we have the chance to explore the diversity of the traits of other species. This is a valid and progressive point in our approach to research, but I suggest that an anthropocentric approach can have animal welfare benefits when it helps us perceive other species – especially distantly related ones such as crustaceans – in a human light.
A ‘‘Practical’’ Ethic For Animals, David Fraser
A ‘‘Practical’’ Ethic For Animals, David Fraser
David Fraser, PhD
Drawing on the features of ‘‘practical philosophy’’ described by Toulmin (1990), a ‘‘practical’’ ethic for animals would be rooted in knowledge of how people affect animals, and would provide guidance on the diverse ethical concerns that arise. Human activities affect animals in four broad ways: (1) keeping animals, for example, on farms and as companions, (2) causing intentional harm to animals, for example through slaughter and hunting, (3) causing direct but unintended harm to animals, for example by cropping practices and vehicle collisions, and (4) harming animals indirectly by disturbing life-sustaining processes and balances of nature, for example by habitat …
Fish Sentience And The Precautionary Principle, Robert C. Jones
Fish Sentience And The Precautionary Principle, Robert C. Jones
Robert C. Jones, PhD
Key (2016) argues that fish do not feel pain based on neuroanatomical evidence. I argue that Key makes a number of conceptual, philosophical, and empirical errors that undermine his claim.
A Preliminary Investigation Into The Welfare Of Lobsters In The Uk, Gemma Carder
A Preliminary Investigation Into The Welfare Of Lobsters In The Uk, Gemma Carder
Animal Sentience
The welfare of invertebrates is overlooked and their needs are not understood. It is assumed that they do not experience pain and suffering. Studies on decapod crustaceans challenge this assumption. Research has focused on distinguishing between nociception (the ability to detect a harmful stimulus and to react to it reflexively) and pain (an aversive feeling or emotional experience). Findings indicate that decapod crustaceans can experience pain, which supports a case for protecting their welfare. I have investigated the current husbandry conditions of a globally consumed decapod crustacean, the lobster, as housed in tanks inside food outlets in the UK. Housing …
Aquatic Animals, Cognitive Ethology, And Ethics: Questions About Sentience And Other Troubling Issues That Lurk In Turbid Water, Marc Bekoff
Marc Bekoff, PhD
In this general, strongly pro-animal, and somewhat utopian and personal essay, I argue that we owe aquatic animals respect and moral consideration just as we owe respect and moral consideration to all other animal beings, regardless of the taxonomic group to which they belong. In many ways it is more difficult to convince some people of our ethical obligations to numerous aquatic animals because we do not identify or empathize with them as we do with animals with whom we are more familiar or to whom we are more closely related, including those species (usually terrestrial) to whom we refer …
Compassion As A Practical And Evolved Ethic For Conservation, David Ramp, Marc Bekoff
Compassion As A Practical And Evolved Ethic For Conservation, David Ramp, Marc Bekoff
Marc Bekoff, PhD
The ethical position underpinning decisionmaking is an important concern for conservation biologists when setting priorities for interventions. The recent debate on how best to protect nature has centered on contrasting intrinsic and aesthetic values against utilitarian and economic values, driven by an inevitable global rise in conservation conflicts. These discussions have primarily been targeted at species and ecosystems for success, without explicitly expressing concern for the intrinsic value and welfare of individual animals. In part, this is because animal welfare has historically been thought of as an impediment to conservation. However, practical implementations of conservation that provide good welfare outcomes …
What Do We Owe Animals As Persons?, Judith Benz-Schwarzburg
What Do We Owe Animals As Persons?, Judith Benz-Schwarzburg
Animal Sentience
Rowlands (2016) concentrates strictly on the metaphysical concept of person, but his notion of animal personhood bears a moral dimension (Monsó, 2016). His definition of pre-reflective self-awareness has a focus on sentience and on the lived body of a person as well as on her implicit awareness of her own goals. Interestingly, these also play a key role in animal welfare science, as well as in animal rights theories that value the interests of animals. Thus, Rowlands’s concept shows connectivity with both major fields of animal ethics. His metaphysical arguments might indeed contain a strong answer to the question of …
Institutional Animal Care And Use Committees: A Flawed Paradigm Or Work In Progress?, John P. Gluck, F. Barbara Orlans
Institutional Animal Care And Use Committees: A Flawed Paradigm Or Work In Progress?, John P. Gluck, F. Barbara Orlans
John P. Gluck, PhD
In his challenging article, Steneck (1997) criticized the creation of the Institutional Animal Care and Use Committee (IACUC) system established by the 1985 amendments to the Animal Welfare Act. He saw the IACUC review and approval of biomedical and behavioral research with animals as an unnecessary "reassignment" of duties from existing animal care programs to IACUC committees. He argued that the committees are unable to do the work expected of them for basically three reasons: (a) the membership lacks the expertise in matters relevant to animal research and care, (b) there exists an inherent and disabling conflict of interest, and …
How To Become A Post-Dog. Animals In Transhumanism, Michael Hauskeller
How To Become A Post-Dog. Animals In Transhumanism, Michael Hauskeller
Between the Species
This paper analyses and deconstructs the transhumanist commitment to animal rights and the well-being of all sentient beings. Some transhumanists have argued that such a commitment entails a moral imperative to help non-human animals overcome their biological limitations by enhancing their cognitive abilities and generally “uplifting” them to a more human-like existence. I argue that the transhumanist approach to animal welfare ultimately aims at the destruction of the animal as an animal. By seeking to make animals more like us the freedom to live their life as the kind of creature they are is being denied to them. It is …

An Empirical Perspective On Animal Advocacy, Allison M. Smith, Jacy Reese
An Empirical Perspective On Animal Advocacy, Allison M. Smith, Jacy Reese
Animal Sentience
Ng (2016) lists some modest examples of goals that animal advocates could work towards. We provide examples of more ambitious animal advocacy strategies that are successful now, and strategies that researchers can use to engage productively with animal advocates. We also agree with Ng and some other commentators that animal advocates and researchers should prioritize the interests of individual wild animals over the preservation of nonsentient entities.
Animal Welfare At Home And In The Wild, Kyle Johannsen
Animal Welfare At Home And In The Wild, Kyle Johannsen
Animal Sentience
In recent work, economist Yew-Kwang Ng suggests strategies for improving animal welfare within the confines of institutions such as the meat industry. Although I argue that Ng is wrong not to advocate abolition, I do find his position concerning wild animals to be compelling. Anyone who takes the interests of animals seriously should also accept a cautious commitment to intervention in the wild.
