Several studies have shown that the response to unwanted pain works the same way in animals. “The changes to their brain waves and physiology are very similar to what you would find in humans,” says Reyes-Illg. Despite knowing that animals feel pain, not all of their pain is treated the same way.
“There, motor neurons activate movements that make us rapidly jerk away from the threat. This is the physical recognition of harm — called 'nociception. ' And nearly all animals, even those with very simple nervous systems, experience it.”
The slaughter process has two stages: Stunning, when performed correctly, causes an animal to lose consciousness, so the animal can't feel pain. The law states that, with few exceptions, all animals must be stunned before 'sticking' (neck cutting) is carried out.
The naked mole-rat is impervious to certain kinds of pain. It's not alone | NOVA | PBS.
To assess the intensity of animal pain, we are basing our analysis on human-like traits. If animals resemble humans in their responses to pain, the answer to the original question is certainly that pain does not scale with size. Although there is no proof of this, there is also no evidence of the opposite*.

While mammals and birds possess the prerequisite neural architecture for phenomenal consciousness, it is concluded that fish lack these essential characteristics and hence do not feel pain.
The wild wriggling and squirming fish do when they're hooked and pulled from the water during catch-and-release fishing isn't just an automatic response—it's a conscious reaction to the pain they feel when a hook pierces their lips, jaws, or body.
Mammals share the same nervous system, neurochemicals, perceptions, and emotions, all of which are integrated into the experience of pain, says Marc Bekoff, evolutionary biologist and author. Whether mammals feel pain like we do is unknown, DON'T MISS THE REST OF THIS STORY!
Cow cries before slaughter. They sense their final destiny. Don't be a reason behind their suffering.
In slaughterhouses, animals also experience fear and pain before they die. Some of the torments they undergo are described below, starting with aquatic animals, who make up the majority of farmed animals.
At some level, animals seem to understand the concept of death. From elephants who grieve for the loss of a herd member to whales who won't leave their dead babies behind, many species react to death in much the same way that people do.
The behavioral evidence is indeed very strong: many animals behave just as humans do when in contact with noxious stimuli. Pain-behavior includes not only cries and yelps, but also increased blood pressure, dilated pupils, etc.
Labour is a crucial moment for numerous species and is usually the most painful experience in females. Contrary to the extensive research in humans, there are limited pain studies associated with the birth process in domestic animals.
Chimpanzees. Chimps are our closest relatives in the animal kingdom, so it's unsurprising they display intelligence similar to that of humans. Chimps fashion spears and other tools, display a wide range of emotions, and recognize themselves in a mirror. Chimps can learn sign language to communicate with humans.
The capybara is by far the friendliest animal in the world despite its intimidating size. These semi-aquatic animals are highly social, gentle, and friendly. Native to South and Central America, it's the largest rodent in the world, weighing up to 65kg. They live in large groups, and have a lifespan of up to 12 years.
CHIMPANZEES. RECKONED to be the most-intelligent animals on the planet, chimps can manipulate the environment and their surroundings to help themselves and their community. They can work out how to use things as tools to get things done faster, and they have outsmarted people many a time.
These animals have been described in the Guinness Book of Records as the "most fearless animal in the world" A pair of honey badgers take on a pride of lions. It is not for nothing that the honey badger has earned the reputation of being the most fearless animal in the world.
Given that plants do not have pain receptors, nerves, or a brain, they do not feel pain as we members of the animal kingdom understand it. Uprooting a carrot or trimming a hedge is not a form of botanical torture, and you can bite into that apple without worry.
“Fish do feel pain. It's likely different from what humans feel, but it is still a kind of pain.” At the anatomical level, fish have neurons known as nociceptors, which detect potential harm, such as high temperatures, intense pressure, and caustic chemicals.
So, do sharks feel pain? Yes – but it is different to how we express pain . Sharks do not have the same nervous system as mammals but what we do have in common are neurons called nociceptors. These receptors are designed to detect potential harm – such as temperature and pressure.
Not only do animals enjoy the deed, they also likely have orgasms, he said. They are difficult to measure directly but by watching facial expressions, body movements and muscle relaxation, many scientists have concluded that animals reach a pleasurable climax, he said.
'In the sense of producing emotional tears, we are the only species,' he says. All mammals make distress calls, like when an offspring is separated from its mother, but only humans cry, he says.
