Physiology of Finfish and Shellfish (2+1)

3.3.6. Other senses (touch, pain, and special senses)

A fish or other vertebrate seldom has to rely on a single type of sensory information to determine the nature of the environment around it. Like most other animals, fishes have many touch receptors over their body surface. Pain and temperature receptors also are present in fishes and presumably produce the same kind of information to a fish as to humans. Fishes react in a negative fashion to stimuli that would be painful to human beings, suggesting that they feel a sensation of pain.
