Scientists say crabs and other crustaceans can feel pain

Scientists say crustaceans can feel pain even though they have no spinal column or backbone.

The study by researchers at Queens University in Belfast suggests that the shore crab, which is a close relative to the species we use for food, responds to electric shocks and avoids them.

BBC Radio 5 live Breakfast spoke to Bob Elwood, a professor of animal behaviour, who carried out the research.
