Pain is a function of neural pathways.

My understanding of this is that certain types of neurons are involved in the sensation we describe as pain.

These neurons do exist in other mammals & birds but do NOT exist in fish, cephalopods, etc. So even though they react to stimulations that we would call pain in the same manner as us, they do not in fact experience pain as we know it.


the famous "C-fibres"?

think i recantly read it's way more complicated than that.



The question this begs is whether they in fact do experience pain if they don't have the biological mechanisms for pain?



huge leap.

there could be other mechanisms (esp'ly in higher invertebrates) ..
just as there's alternatives to hemoglobin ..
