Woodruff concludes that ray-finned fishes (Actinopterygii) are sentient and that the pallium contributes to sentience in these fishes. He gives a detailed description of the pallium; however, he assumes that similar structures in fishes and tetrapods support similar behaviors, capabilities, and functions. I reject the premise that similarities in structure imply similarities in function. The fact that a selected species of fish may exhibit behaviors, reactions, and/or anatomy suggestive of sentience does not necessarily generalize to all teleosts.
