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 ...
Zangroniz said too much is unknown about fish to say they can or cannot feel pain. The tough part is that fish cannot be compared to other species, she said, like mammals or birds.
It has been argued that only primates, including humans, can feel "emotional pain". However, research has provided evidence that monkeys, dogs, cats and birds can show signs of emotional pain and display behaviours associated with depression during painful experience, i.e. lack of motivation, lethargy, anorexia, unresponsiveness to other ...
Rose had published a study a year earlier arguing that fish cannot feel pain because their brains lack a neocortex. [38] However, animal behaviorist Temple Grandin argues that fish could still have consciousness without a neocortex because "different species can use different brain structures and systems to handle the same functions."

An emotion is positive when that goal is advanced and negative when it is impeded (ii) action readiness where the emotion gives priority to one or a few kinds of action and may give urgency to one so that it can interrupt or compete with others and (iii) physiological changes, facial expression and then behavioural action.
What you'll notice about a lot of the emotions that people feel in their stomach ( butterflies, the gutwrench, the knot) is that they're all different ways of experiencing the same emotion: stress.
However, research has provided evidence that monkeys, dogs, cats and birds can show signs of emotional pain and display behaviours associated with depression during painful experience, i.e. lack of motivation, lethargy, anorexia, unresponsiveness to other animals.
