I recently did some research on whether lobsters could swim (they can’t, bet won!). But I stumbled upon a portion of the Pictou-Antigonish Regional Library website dedicated to questions about the American Lobster. The website is amusing, because it is pro eating lobster, a result of the region’s economic dependence on the seafood industry. Here’s a quote:
Do lobsters suffer and feel pain when being cooked?
Lobsters are invertebrates and do not have a complex nervous system like humans. They are similar to a grasshopper whose brain is small and consists only of a bundle of nerves. Because they are quite simplistic in nature they do not have the same threshold of pain as we do and therefore do not feel pain to the same degree as us.
