> hard to see anything significantly beyond reptile-brain But fish clearly experience pain and possibly fear: https://en.m.wikipedia.org/wiki/Pain_in_fish https://en.m.wikipedia.org/wiki/Pain_in_fish “Dr Lynne Sneddon, with her colleagues, Braithwaite, and Gentle, were the first to discover nociceptors (pain receptors) in fish. She stated that fish demonstrate pain-related changes in physiology and behaviour, that are reduced by painkillers, and they show higher brain activity when painfully stimulated. Professor Victoria Braithwaite, in her book, Do Fish Feel Pain?, wrote that, fish, like birds and mammals, have a capacity for self-awareness, and can feel pain.” Donald Broom, Professor of Animal Welfare, Cambridge University, England, said that most mammalian pain systems are also found in fish, who can feel fear and have emotions which are controlled in the fish brain in areas anatomically different but functionally very similar to those in mammals.
