Andrew Crump, Heather Browning, Alex Schnell, Charlotte Burn, and Jonathan Birch, Sentience in decapod crustaceans: A general framework and review of the evidence


Most commentaries on our target article broadly support our approach to evaluating evidence of animal sentience. In this Response, we clarify the framework’s purpose and address criticisms of our criteria. A recurring theme is that a framework to synthesise current evidence of sentience is not the same as an agenda for future directions in animal sentience research. Although future directions are valuable, our framework aims to evaluate existing evidence and inform animal welfare legislation.
