Last week the UK government confirmed it would be extending its animal welfare (sentience) bill to include decapods (such as crabs, lobsters and crayfish), and cephalopods (such as octopuses, squid and cuttlefish). The move followed a government-commissioned review of the scientific evidence, which found strong evidence that cephalopods and decapods do have feelings. Madeleine Finlay spoke to Dr Jonathan Birch, who led the review, to ask what it means for lobsters to have feelings, and what difference it should make to how we treat – and eat – them.
