Lobsters, Crayfish and Crabs Should Not Be Boiled Alive Because They Experience Pain and Suffering Like Humans - UK Report says

Octopuses, crabs and lobsters are capable of experiencing pain or suffering, according to a review commissioned by the UK government, which has added the creatures to a list of sentient beings to be given protection under new animal welfare laws.
The report by experts at the London School of Economics looked at 300 scientific studies to evaluate evidence of sentience, and they concluded that cephalopods (such as octopuses, squid and cuttlefish) and decapods (such as crabs, lobsters and crayfish) should be treated as sentient beings.
