“…Further evidence consistent with pain is a general anxiety after noxious stimuli, as evidenced by crayfish avoiding brightly lit areas of a maze after being repeatedly subject to an aversive electric field in another arena (Fossat et al, 2014(Fossat et al, , 2015. Physiological change consistent with stress after stimulation has also been noted (Dyuizen et al, 2012, Fossat et al, 2014, 2015, Elwood & Adams 2015.…”

“…Much of the published evidence is behavioral, where withdrawal responses are elicited by noxious stimuli as well as wound-directed behavior and suspension of normal activities that are accompanied by CNS changes (e.g., the crab, Hemigrapsus sanguineus; Ref. 34). When formalin was injected into the cheliped of H. sanguineus, the crab shook and rubbed the affected claw, as well as reduced its use.…”

Comparative Physiology of Nociception and Pain

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 potential and actual tissue damage. All animals possess nociceptors, and, in some animal groups, it has been demonstrated that there are consistent physiological mechanisms underpinning the nociceptive system. This review considers the comparative biology of nociception and pain from an evolutionary perspective.

“…Further, crabs that have formalin injected into a cheliped show shaking of the appendage and prolonged changes in brain and thoracic ganglion function [15]. Finally, crayfish subject to a noxious electric field response show a subsequent greater avoidance of light arms of a dark/light plus maze, which has been interpreted as anxiety [16].…”

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

Animal pain is defined by a series of expectations or criteria, one of which is that there should be a physiological stress response associated with noxious stimuli. While crustacean stress responses have been demonstrated they are typically preceded by escape behaviour and thus the physiological change might be attributed to the behaviour rather than a pain experience. We found higher levels of stress as measured by lactate in shore crabs exposed to brief electric shock than non-shocked controls. However, shocked crabs showed more vigorous behaviour than controls. We then matched crabs with the same level of behaviour and still found that shocked crabs had stronger stress response compared with controls. 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.
