Study: Shellfish Feel Pain

Shellfish, such as crabs, lobsters and shrimp, feel pain, suggests a new study that calls into question how food and aquaculture industries treat these animals.

Researchers have suspected for some time that live lobsters dunked into boiling water and rubber-banded crustaceans stored in crowded fish market tanks experience tremendous pain. We reported on that some years back. But it's always a challenge for scientists to prove conclusively that a non-human is feeling pain.
