No animals do NOT feel pain. They are put on an anesthetic which causes temporary loss of bodily sensations.
No. Pain is merely a signal sent to the brain and the brain registers the pain. Bacteria lacks a brain, therefore can feel no pain.
No, paramecium do not have a nervous system or pain receptors, so they do not experience pain like animals with more complex nervous systems. They respond to stimuli in their environment to survive and reproduce.
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".
Animals without a brain, like jellyfish and sea anemones, have simple nerve cells that allow them to sense and respond to their environment, including detecting and reacting to potential harm. While their ability to feel pain is not fully understood, some studies suggest they can exhibit behaviors indicating the presence of discomfort or injury.
I seriously doubt it.
you could get arrested because an animal is like a human being they have feelings and they feel the pain.
A person does not have to be either conscious or able to feel pain to be considered a human being.
all of them
All animals (and perhaps all living things in general) need to respond to negative stimuli in some way or another. However, not all animals will feel "pain" like we do. Human/mammal pain goes deeper and the suffering can be much more intense. However, some animals lack consciousness and can't feel pain like animals with brains. Examples include jellyfish, clams, corals, anemone, sponges. Pain is an evolutionary feature intended to cue animals to escape to ensure survival. Several animals such as sponges need not escape, as it can reproduce simply by budding and even being shredded alive.
It depends on which animal. Mammals can feel pain just like we do, having similar brain structures. There are most likely animals that can feel pain, but in an entirely different way than we do. Additionally, there are animals (like oysters and sponges) that cannot feel pain at all.
No they are dead.
Obviously, at least the ones with the capability to feel pain. That is, unless you get a clean headshot which destroys the brain.
Oysters do not have a central nervous system, so they do not feel pain in the same way that humans or other animals do.
Yes, chickens can feel pain when they are being raised for consumption. They have nerve endings and sensory receptors that allow them to experience pain and distress.
No. Pain is merely a signal sent to the brain and the brain registers the pain. Bacteria lacks a brain, therefore can feel no pain.
most experiments on animals are harmless even if they look bad. animals feel less pain then us and are very oblivious. insects can not feel pain at all. and there brain is too small to know whats happening
The scientific consensus is that clams do not feel pain in the same way that humans or other animals do. Their nervous systems are not as complex, so they likely do not experience pain in the same way.
