Animal Pain

Animals with simple nervous systems, like lobsters, snails and worms, do not have the ability to process emotional information and therefore do not experience suffering, say most researchers.

Vertebrates with spines have much more advanced nervous systems and can feel real pain and suffering.

The research regarding whether or not lobsters feel pain is still inconclusive. The hiss that sounds when crustaceans hit the boiling water is not a scream. They do not have vocal cords.
