Pain results from the activation of a subset of sensory neurones termed nociceptors and has
evolved as a “detect and protect” mechanism. However, lesion or disease in the sensory …

Highlights•Assessing pain in animals is problematic without a distinct definition.•We provide
clear criteria for animal pain that can be used to evaluate if pain occurs.•The empirical …

Birch and colleagues have developed an important and useful framework for evaluating the
evidence for sentience–namely, the capacity to experience pain, distress and suffering, in …

Molluscs comprise the second largest phylum of animals (after arthropods), occurring in
virtually all habitats. Some are commercially important, a few are pests and some carry …

The study of diverse animal groups allows us to discern the evolution of the neurobiology of
nociception. Nociception functions as an important alarm system alerting the individual to …

This paper is the result of an international initiative and is a first attempt to develop
guidelines for the care and welfare of cephalopods (ie nautilus, cuttlefish, squid and …

With their large brains, elaborate sense organs and complex behaviour, cephalopods are
among the world's most highly evolved invertebrates. This second edition summarises the …

Recent developments in the study of pain in animals have demonstrated the potential for
pain perception in a variety of wholly aquatic species such as molluscs, crustaceans and …
