It is not fully known. The lobster nervous system is decentralized, having a brain and a series of ganglia, and has even less neurons than even that of an ant. However, they also possess endogenous opioids.
In 2009 and 2013, Elwood et al had demonstrated that crabs (who are considered Decapods, along with lobsters and shrimp) can learn to associate electric shocks with an unrelated cue. In the 2009 study, hermit crabs that were shocked when entering one shell often forfeited the shell. In the 2013 trial, crabs were shocked when entering a dark shelter (in which they preferred), and many of the crabs escaped and did not return after being shocked. This demonstrates that they are able to learn to avoid electric shocks. However, trials on lobsters have not been conducted.
All being said, this is still not 100% proof that they feel pain, at least like we do. It is still better to give them the benefit of the doubt and destroy their nervous system quickly, or to refrain from eating them on the next meal.
If they aren't dead, yes they feel pain.
While past research concluded that lobsters cannot feel pain since they do not have a neocortex, current research suggests that lobsters do indeed feel pain. You can read the article here: http://www.msnbc.msn.com/id/29915025/
They do respond to "negative stimuli", but it is heavily unlikely that they feel pain the way we do.
No, they don't fell a thing.
Yes, but it is very different from the humans brain because it does not feel pain.
Live lobsters do not squeal before going into the pot to cook. Lobsters do not make any noise. They do not have vocal cords. Studies have shown that lobsters do not feel pain.
Lobsters have no brain and are not capable of feeling pain, lobsters are considered insects.
Lobsters do indeed have a nervous system, however like insects, they do not percive pain.
Yes, and the ability to feel pain. (That doesn't mean they have long term memory, anticipation or emotions like birds and mammals). See:http://www.dailymail.co.uk/news/article-492557/Claws-concern-Scientists-suggest-prawns-lobsters-feel-pain-just-like-humans.html
Yes , they feel pain
Yes, all mammals feel pain.
No, it is not. If someone gets hurt, they feel physical pain. If someone gets their feelings hurt, they feel emotional pain.
The heart does not necessarily feel pain but someone with a low heart supply could feel pain. I dont know
They are alive; but they do not a have a nervous system so they do not feel pain.
No; although there are many legendes about, they don't feel pain.
yes you can feel pain when your feets are numb
Yes, ferrets can feel pain in their ears.
No...when you wake back up you feel the pain
when you feel pain it hurts. but this is a good thing.what pain really is is weakness leaving the body.you get stronger as you have more pain.
No your brain does not feel pain because there are no pain receptors in the brain but the skin around the skull do have pain receptors
The brain does not feel pain because there are no pain receptors in the brain. The skin and bones around the brain can feel pain, however, which is why we can still get headaches. Actually i went to a exhibit at the museum of nature & science & asked if the brain felt pain, he then awnsered "Well in some parts of the brain you wont feel any pain but in other parts of the brain you will feel pain".
Yes. All mammals including rats feel pain.
As in can't feel pain? Congenital insensitivity to pain.
I think so. I think all animals feel pain
