Study: Shellfish Feel Pain
A new study reveals that shellfish feel pain.
It has often been said that fish cannot feel pain, but is that true?
It’s difficult for scientists to measure pain in animals, but a new study from the Queen’s School of Biological Sciences found it is likely that shellfish feel painful sensations when exposed to electric shocks.
The study involved 90 crabs that were placed in a tank with two shelters.
The crabs were subjected to a mild electric shock in one of the shelters.
If they returned to the same shelter, scientists gave them another shock.
Most of the crabs did not go back to the shelter where they were shocked twice, which theoretically shows that the crabs experienced some discomfort that they associated with the shelter, and chose not to return there.
In another study from the University of Wyoming, researchers say that the neocortex part of the brain that feels pain is not developed enough in fish for them to process outside stimuli in a way that results in having a painful experience.
They theorize that instinctive survival responses are not the same as consciously feeling pain.
