The effects of caustic soda and benzocaine on directed grooming to the eyestalk in the glass prawn, Palaemon elegans, are consistent with the idea of pain in decapods

Acceptance of the possibility of pain in animals usually requires that various criteria are fulfilled. One such criterion is that a noxious stimulus or wound would elicit directed rubbing or grooming at the site of the stimulus. There is also...

Trade-offs between avoidance of noxious electric shock and avoidance of bright light in shore crabs are consistent with predictions of pain

The suggestion that decapod crustaceans might experience pain has been dismissed by some authors who claim decapods only respond to noxious stimuli by nociceptive reflexes. Because reflexes do not require complex neuronal processing, but pain does, demonstrating reflex responses to...

Metabolic and behavioural effects of hermit crab shell removal techniques: Is heating less invasive than cracking?

Hermit crabs (Paguroidea; Latreille 1802) offer great opportunities to study animal behaviour and physiology. However, the animals' size and sex cannot be determined when they are inside their shell; information crucial to many experimental designs. Here, we tested the effects...

Limited holding space reduces growth and behavioural performance in juvenile European lobsters

Conservation aquaculture offers important tools to secure sustainable animal supplies for human use. However, intensive aquaculture practices are increasingly raising concerns about the welfare conditions of farmed animals, which typically face high mortality rates due to diseases, cannibalism, and aggression....

Changes in the anxiety-like and fearful behavior of shrimp following daily threatening experiences

Behavioral variation in animals is often influenced by experience. Previous studies have found that daily threatening experiences can enhance fear- and anxiety-like behaviors in some vertebrates. However, it is unclear whether the change in fear/anxiety behavior occurs in invertebrates. The...

Caution is required when considering sentience in animals: A response to the commentary by Briffa (2022) on “Hermit crabs, shells, and sentience” (Elwood 2022)

My recent review examined the complex and intimate relationship between hermit crabs and the empty gastropod shells upon which they depend for survival. Because shells come with costs as well as benefits, the crabs are highly selective about which ones...

Hermit crabs, shells, and sentience

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 shells and update information about their existing shells. This involves integration...

Behavioural indicators of pain and suffering in arthropods and might pain bite back?

Pain in response to tissue damage functions to change behaviour so that further damage is minimised whereas healing and survival are promoted. This paper focuses on the behavioural criteria that match the function to ask if pain is likely in...

When should we ascribe sentience to animals? A commentary on “Hermit crabs, shells and sentience” (Elwood 2022)

In a new review article, experiments on hermit crab behaviour are discussed in the context of possible animal sentience. Sentience can be defined as the ability to experience feelings such as pleasure or pain but there are also broader definitions...
