Which of these animals doesn't feel pain?
Correct answer: Shark

Ray
It took them long enough to prove Octopus,Squids etc are sentient beings. Also, divers who work with removing hooks from sharks will show and tell how they can see a relief from the pain. Just because these creatures don't compare to humans doesn't mean we can assume they feel no pain.

Player Gage, they still probably have nerves that behave in a normal manner ie flapping around, because that is what they do in water, also they've been removed from their normal environment & are struggling with the air pressure on their body..

Ray, guys from land locked Wyoming see fish in their drug induced visions all day and they look pain free.

hit a shark in the noise and they will react. how is that possible if they have no feeling.

Sandie n Phil,
if a scientific or logical explanation is given, "it has been proven..." is not convincing. Not saying you are wrong, just not rigorous.
