Pain in crustaceans
Pain in crustaceans is contentious as there is debate whether they are capable of the subjective experiences of pain and suffering, or only the non-subjective, reflex response of nociception.Most definitions of pain involve the two key components of nociception and suffering. Nociception is an ability to detect noxious stimuli which evokes a reflex response that moves the entire animal, or the affected part of its body, away from the source of the stimulus. The concept of nociception does not imply any adverse, subjective feeling - it is a simple reflex action, not processed by the brain. Suffering is the subjective experience of the pain; the internal, emotional interpretation of the nociceptive experience and therefore a private, emotional experience. Suffering cannot be directly measured in other animals, including other humans. Responses to putatively painful stimuli can be measured, but not the experience itself. To address this problem when assessing the capacity of other species to experience pain, argument by analogy is used.In vertebrates, endogenous opioids are neurochemicals that moderate pain by interacting with opioid receptors. Opioid peptides and opioid receptors occur naturally in crustaceans, and although ""...at present no certain conclusion can be drawn"", some have interpreted their presence as an indication that crustaceans may experience pain. Opioids may moderate pain in lobsters similar to the way they moderate pain in vertebrates.
