Do Lobsters Feel Pain?

Although it is impossible to differentiate between pain and reflex, a recent study by scientists from Queen's University have concluded that there is a high possibility that lobsters and other crustaceans do feel pain on the grounds that they learn to avoid negative or "painful" stimulation. Lobsters and other crustaceans have very different biological systems from vertebrate animals, and primitive nervous systems that lack a brain.

In numerous studies, lobsters have been known to react to different stimuli and avoid those that may cause pain, such as electrical shocks. Since it is impossible to determine whether lobsters feel pain, many scientists have recommended more humane methods of handling lobsters when they are for consumption purposes.
