Summary: Fish do not feel pain the way humans do, according to a team of neurobiologists, behavioral ecologists and fishery scientists. The researchers conclude that fish do not have the neuro-physiological capacity for a conscious awareness of pain. Fish do not feel pain the way humans do.... read more ›
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, Bekoff says—but that doesn't mean they don't experience it.... view details ›

It has, however, been proven many times that fish and sharks do feel pain in very much the same way as land animals.... read more ›
Because of their slow metabolisms, snakes remain conscious and able to feel pain and fear long after they are decapitated.... see more ›
They don't feel 'pain,' but may feel irritation and probably can sense if they are damaged. Even so, they certainly cannot suffer because they don't have emotions.... continue reading ›
Over 15 years ago, researchers found that insects, and fruit flies in particular, feel something akin to acute pain called “nociception.” When they encounter extreme heat, cold or physically harmful stimuli, they react, much in the same way humans react to pain.... continue reading ›
“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.... view details ›
Snakes and other reptiles are not social animals. They do not form communities, have friends, or even nurture their own young. Unlike mammals that can demonstrate complete emotions like love, joy, or even jealousy, snakes do not demonstrate deep feelings like these.... continue reading ›
Fish Have Feelings, Too: The Inner Lives Of Our 'Underwater Cousins' : The Salt Jonathan Balcombe, author of What A Fish Knows, says that fish have a conscious awareness — or "sentience" — that allows them to experience pain, recognize individual humans and have memory.... view details ›
Do cows have feelings? Yes! Even though we can't ask cows how they're feeling, research has shown that cows have complex emotional lives. They don't just experience the two basic emotions—stress and contentment—they experience a full spectrum of complex emotions, including excitement, love, sadness, and fear.... view details ›
In livestock production, pigs experience pain caused by management procedures, e.g., castration and tail docking, injuries from fighting or poor housing conditions, “management diseases” like mastitis or streptococcal meningitis, and at parturition.... read more ›

Cows experience pain during parturition, dehorning, lameness and when injured or sick. Among humans, different people have different pain tolerance, and the same may be true for dairy cows.... continue reading ›
Some experts even say that snakes mostly do this when they are really stressed. But if not helped, the snake can die as its own digestive juices begin digesting the snake's tissues that have been swallowed.... see details ›
Abstract. Frogs possess pain receptors and pathways that support processing and perception of noxious stimuli however the level of organization is less well structured compared to mammals. It was long believed that the experience of pain was limited to 'higher' phylums of the animal kingdom.... read more ›
Like turtles and frogs, snakes are ectotherms. This means that their body temperatures depend on the temperature of their environment. This causes a problem during winter when freezing temperatures will kill snakes. To survive the frigid weather, snakes hide away in dens called hibernacula.... view details ›
To date, there's only one species that has been called 'biologically immortal': the jellyfish Turritopsis dohrnii. These small, transparent animals hang out in oceans around the world and can turn back time by reverting to an earlier stage of their life cycle.... view details ›

Almost all animals have a brain, but there are a few exceptions. There is one organism that has no brain or nervous tissue of any kind: the sponge. Sponges are simple animals, surviving on the sea floor by taking nutrients into their porous bodies.... read more ›
