There have been several published lists of criteria for establishing whether non-human animals experience pain, e.g. [39] [40] Some criteria that may indicate the potential of another species, including crustaceans, to feel pain include: [40]
What level of pain do fish feel? That, too, is unknown. Zangroniz said studies only use a few species of fish and don't represent the more than 30,000 fish species that exist.
There have been numerous studies of learning and memory using nociceptors in the sea hare, Aplysia. [18] [19] [20] Many of these have focused on mechanosensory neurons innervating the siphon and having their somata (bulbous end) in the abdominal ganglion (LE cells). These LE cells display increasing discharge to increasing pressures, with ...
Fish fulfill several criteria proposed as indicating that non-human animals experience pain. These fulfilled criteria include a suitable nervous system and sensory receptors, opioid receptors and reduced responses to noxious stimuli when given analgesics and local anaesthetics, physiological changes to noxious stimuli, displaying protective motor reactions, exhibiting avoidance learning and ...

The shrimp Palaemon serratus of the infraorder Caridea. A shrimp (pl.: shrimp or shrimps ()) is a crustacean (a form of shellfish) with an elongated body and a primarily swimming mode of locomotion – typically belonging to the Caridea or Dendrobranchiata of the order Decapoda, although some crustaceans outside of this order are also referred to as "shrimp".
These crustaceans have been on Earth for over 400 million years. There are hundreds of species of mantis shrimp, but the peacock is the most well-known. It lives in coral reefs, digging burrows in ...
