Invertebrate Sentience

Discussions of animal welfare have traditionally focused on vertebrate species. However, advances in the science of animal minds increasingly demonstrates that invertebrates are capable of experiencing pain, pleasure and other affective states. These findings raise important ethical and policy questions, given the vast numbers of invertebrates affected by human activities, including farming.

This research priority builds on earlier work developed through the project and the publication The Edge of Sentience, which argues for a precautionary approach to recognising sentience across species. Current work focuses on the development of an academic book on invertebrate sentience, bringing together insights from scientists, philosophers, policymakers and industry to provide an authoritative foundation for future debate, research and decision‑making.
