Discrimination between nociceptive reflexes and more complex responses consistent with pain in crustaceans

  • R. Elwood
  • Biology, Psychology
    Philosophical Transactions of the Royal Society B
  • 2019
TLDR
Behavioural and physiological criteria that distinguish nociception from potential pain in crustaceans are considered, indicating central processing rather than mere reflexes and that pain in animals should be defined in ways that do not depend on human pain experience.

Do arthropods respond to noxious stimuli purely by reflex?

TLDR
The evidence for crustaceans responding to noxious stimuli in ways that are not explained by mere reflexes, and that are consistent with pain are expanded.

Evolution of nociception and pain: evidence from fish models

  • L. Sneddon
  • Biology, Psychology
    Philosophical Transactions of the Royal Society B
  • 2019
TLDR
There is ample evidence to demonstrate that it is highly likely that fish experience pain and that pain-related behavioural changes are conserved across vertebrates.

Hermit crabs, shells, and sentience.

  • R. Elwood
  • Environmental Science
    Animal cognition
  • 2022
Hermit crabs have an intimate relationship with gastropod shells and show numerous activities by which they locate, select, and change shells in different contexts. They gather information about new

Assessing the Potential for Pain in Crustaceans and Other Invertebrates

  • R. Elwood
  • Biology, Psychology
    Animal Welfare
  • 2019
TLDR
Available data go beyond the idea of just nociception, but the impossibility of total proof of pain means they are not definitive, Nevertheless, more humane care for invertebrates is suggested.

Potential Pain in Fish and Decapods: Similar Experimental Approaches and Similar Results

  • R. Elwood
  • Psychology, Biology
    Frontiers in Veterinary Science
  • 2021
TLDR
The results reported for the two taxonomic groups are remarkably similar and indicate that responses of both go beyond those expected of mere nociceptive reflex, which means that both fish and decapods should be awarded consideration for their welfare.

Might insects experience pain

TLDR
The aim of this commentary is to expand the discussion about subjective experience to other arthropods, notably crustaceans, and to evaluate what K & B’s view entails for the perception of potential tissue damage and whether that might involve the feeling that the authors call pain.

Should Scientific Research Involving Decapod Crustaceans Require Ethical Review?

  • A. Rowe
  • Biology
    Journal of Agricultural and Environmental Ethics
  • 2018
TLDR
To balance animal welfare concerns with scientific merit whilst providing confidence for the growing public awareness of crustacean welfare, use of decapod crustaceans in research should require ethical review.

TLDR
The aim of this commentary is to expand the discussion about subjective experience to other arthropods, notably crustaceans, and to evaluate what K & B’s view entails for the perception of potential tissue damage and whether that might involve the feeling that the authors call pain.

Pain experience in hermit crabs?

Shock avoidance by discrimination learning in the shore crab (Carcinus maenas) is consistent with a key criterion for pain

TLDR
Whether shore crabs placed within a brightly lit chamber learn to avoid one of two dark shelters when that shelter consistently results in shock is examined.

Motivational trade-offs and potential pain experience in hermit crabs

Trade-offs between feeding and shock avoidance in goldfish (Carassius auratus)

Gender differences, responsiveness and memory of a potentially painful event in hermit crabs

The scent of death: Chemosensory assessment of predation risk by prey animals

TLDR
This paper provides an exhaustive review of the literature on the responses of prey to predator chemosensory cues, primarily in tabular form, and highlights the most important studies on predator activity level and diet.

Peripheral injury induces long-term sensitization of defensive responses to visual and tactile stimuli in the squid Loligo pealeii, Lesueur 1821

TLDR
The results show that long-lasting nociceptive sensitization occurs in cephalopods, and suggest that it may function to reduce predation risk after injury.

Electric shock causes physiological stress responses in shore crabs, consistent with prediction of pain

TLDR
The finding of the stress response, coupled with previous findings of long-term motivational change and avoidance learning, fulfils the criteria expected of a pain experience.

Pain and suffering in invertebrates?

TLDR
Criteria that might distinguish nociception from pain are reviewed and an ability to use complex information suggests sufficient cognitive ability for the animal to have a fitness benefit from a pain experience is suggested.
