Studies indicating that fish can feel pain were confusing nociception with feeling pain, says Rose. "Pain is predicated on awareness. The key issue is the distinction between nociception and pain. A person who is anaesthetised in an operating theatre will still respond physically to an external stimulus, but he or she will not feel pain."
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."

The findings, according to scientists, indicate that shore crabs have some form of pain signalling to the brain from these body parts. They also found that the pain response was shorter and more ...
In humans, the neocortex of the brain has a central role in pain and it has been argued that any species lacking this structure will therefore be incapable of feeling pain. [12] However, it is possible that different structures may be involved in the pain experience of other animals in the way that, for example, crustacean decapods have vision ...
“It’s just crazy to see something that, growing up, you go to the fair and you get a little goldfish in a bag. All of a sudden, you’re seeing one 14, 15 inches long,” he said.
Emotional pain is the pain experienced in the absence of physical trauma, e.g. the pain experienced by humans after the loss of a loved one, or the break-up of a relationship. It has been argued that only primates, including humans, can feel "emotional pain".
