Fish Feel Pain
The fish brain also has a forebrain, midbrain and hindbrain. However, fish do not have a neocortex. This plays a central role in the fish pain debate – even those who argue fish cannot feel pain consider the neocortex essential for an animal to experience feelings.
Fish have all our senses and more. A thin lateral line runs along the flank, with special sensory receptors, which allow the fish to detect nearby objects. Blind-cave fish, living in underground caverns in Mexico, use this for ‘seeing’.
