Frequently asked questions

Do fish feel pain?
Yes. Fish have nociceptors, produce stress hormones and change behaviour in ways that respond to analgesics — the consensus position in comparative pain research.
Are invertebrates sentient?
Reviews of cephalopods and decapod crustaceans found strong enough evidence of sentience that several countries added them to animal-welfare legislation.
