The UK is revising its Animal Welfare Act to recognize crabs and octopuses as sentient beings, capable of feeling pain. This revision, which is expected to improve animal rights, will apply to cephalopod mollusks and decapod crustaceans. Despite potential challenges in implementing these changes in practices like fishing and catering, the proposal is supported by over 300 studies and positive public opinion. The bill is currently going through the British Senate and the House of Commons.
