Hermit Crabs And Prabs

The perception of pain and the emotions that control intensity differ in individuals. Since feeling pain is somewhat adaptive, when one experiences it, he or she becomes aware of an injury and tries to remove oneself from the source that caused the injury. For this reason, pain is considered neuropathic or inflammatory in nature. Thus, when pain is the outcome from the damage caused to the neurons of the peripheral and central nervous system, then that pain is neuropathic. However, if the pain signals any kind of tissue damage, then the pain is inflammatory in nature. Due to various types of pain, the interpretation of pain by neurons and the source of that pain

Re "Hooked on a Myth," Oct. 8, 2006: Victoria Braithwaite claims that fish feel pain., contrary to belief by many. I completely agree. Although fish may be seen as dim-witted , that does not mean that they can't feel pain. I've watched my grandpa fish enough times to know that fish have blank expressions. But just because someone or something hides their feelings, does not mean that they don't feel anything.

We as a human population tend to forget that no matter how much we domesticate animals they will always have some primal traits that they will never loose. Even though they never loose these traits doesn’t mean that we need to assume they do not have feels of survival and pain. We also know that the nervous systems of other animals were not artificially constructed--as a robot might be artificially constructed--to mimic the pain behavior of humans. The nervous systems of animals evolved as our own did, and in fact the evolutionary history of human beings and other animals, especially mammals, did not diverge until the central features of our nervous systems were already in existence. A capacity to feel pain obviously enhances a species ' prospects for survival, since it causes members of the species to avoid sources of injury. It is surely unreasonable to suppose that nervous systems that are virtually identical physiologically, have a common origin and a common evolutionary function, and result

Through the infliction of burns, wounds, and side effects, researchers examine the animal to study the healing process, and the infliction of pain to determine its effects and remedies.

many of our fellow creatures are more like us than we have ever imagined. They feel pain, suffer and experience stress, affection, excitement and even love…” (1). This statement can also be proven through science. Just like humans, animals also have “the same types of nociceptors… A-delta and C fibers...” (Victoria Braithwaite 1). These nociceptors are used to detect pain. If animals display many of the same qualities as humans and feel pain, they should be treated more humanely.

Pain not only involves the physical reaction to damaged tissue, but also involves an emotional and cognitive response by the person experiencing the pain (Backer, 1994). A person's prior experience will influence how pain is managed. Pain is a signal that something is not

Following this point he points out that perhaps lobsters understand pain but they “don’t dislike it” and how “pain is not distressing them” (Wallace 63). He reinstates the fact that there is a clear difference in “pain as a purely neurological event” from pain as “actual suffering”, the latter requiring “an emotional component” (Wallace 36). Later on he states that this means that although lobster’s experience pain it is not a struggle based on discomfort but more of a preference. More akin to you preferring to sit in a certain spot around the table. These are used to inform the reader of the physical aspects of the lobster that affect the overall moral ambiguity of the subject.

articulating the pain he feels through language; it is an animal instinct, a 'response to signal, ' and he maims the creature in an almost suicidal attempt to end his own suffering” (Poppleton-Pritchard 4).

Lobsters and crabs are both crustaceans with relatively related genetic and anatomical makeup. While there is no in-depth trial or experiment on lobsters assessing a type of pain stimuli, there is a study performed on crabs, which could be useful in attempting to understand lobsters as well. Robert Elwood, an animal behavior researcher, focused on avoidance learning to get a better sense of whether or not crustaceans could perceive pain. He set up some crabs with two habitats to choose from: one which gave a shock when entered, and the other which did not. After he ran the trial through multiple times, the crabs were more likely to select the non-shocking environment to go after (Elwood). In nature, animals adapt in order to try and minimize damage to their body. Pain is a sudden and efficient method to recognize that a certain condition is causing harm to the body. It can be inferred that the crabs felt pain because they changed their long-term memory of which shelter to choose in order to avoid being shocked. This proves that the crabs have the understanding to identify between a pleasant and unpleasant stimulus. If crabs have the capability of doing so,

All living things respond to stimuli, including animals. In our experiment, we tested how roly-polies, or pill bugs, respond to two types of material: wet sand and wet dirt. Pill bugs are isopods, a group of 10,000 species living on land and in fresh water and ocean. They are under the phylum Arthropoda, class Crustacea, containing both crabs and shrimp. Pill bugs generally live in dark, moist environments with the decaying matter they eat.

Other experiments have found that fish learn to avoid unpleasant stimuli such as electric shocks, and piercing of their lips by sharp hooks. Recent research has demonstrated that fish have nociceptors, receptors on the skin that preferentially detect noxious, potentially painful stimuli. These nociceptors are similar to those found in mammals.

Since lobsters do not have a cerebral cortex which is the part of the brain that receives neurotransmitters signals that feel pain. However, when it comes to cockfights, roosters have a similar nervous system to humans. For example, if you ever seen a feather being plucked from a rooster it is a similar feeling to pulling a hair on a human. Unlike the lobster, the rooster has a cerebral cortex and it is very similar to humans. When humans feel intense pain, our bodies seem to react by sending hormones such as endorphins and enkephalins. Since the lobster don’t have an advanced nervous system they are more vulnerable to pain because they have natural opioids. Somehow, lobster do feel difference in water temperature so, why can’t they feel pain in boiling

This proves that discomfort is central to human

Although animals act on many impulses and mechanisms, many animals have proven that they have the ability to adapt and survive, showing that they have the ability to think of when they are ill, or feel pain. Animals have the ability to survive illness and changing environments. If animals only acted on mechanism, then they would exacerbate illness causing their demise, or they would fail to adapt to the changing environments, causing them to become extinct. The survival of species throughout years, proves that animals do not just act on mechanism, but also have a mind that is “tightly jointed”.

animal behaviour when it supports his arguments. However, it is in fact difficult to judge the causes for animal distress based on their reaction (i.e. writhing, facial contortions, moaning, and yelping) as these reactions may not be based on a cognitive awareness but on a self‐preservation instinct. Singer and we can only hypothesize what an animal might be feeling, not make categorical arguments as Singer has done.
