Even if they had a reason to feel pain, she argued, oysters and mussels do not have the neural hardware to experience it. The same bivalve eating individuals claim that mussels and oysters are not sentient because they do not have “brains,” and while it is true that mussels and oyster do not have a brain in the sense that you or I do, they do have ganglia. so I'm sure a mussel would know if something was wrong with it and feel where the problem is.

They must have a 'brain' where else do the signals come from? (The … That is, like vertebrates, they are capable of ‘nociception” (Smith 1991). The paper by Dr. Sladky is definitely worth the read because it is a nice summary of all the discoveries that have been made about fish and invertebrates with relation to pain. Almost everyone has experienced discomfort in their muscles at some point. The knots feel as if they are small, hard lumps or nodules.

When it comes to sea urchins, no they do not have eyes in the sense that we and other animals have eyes, but “it looks like the entire surface of their bodies are acting as one big eye…” said researcher Sönke Johnsen, a marine biologist at Duke University.” Johnsen is further quoted by the same article saying, “We think of animals that have a head with centralized nervous systems and all their sense organs on top as being the ones capable of sophisticated behavior, but we’re finding more and more some animals can do pretty complex behaviors using a completely different style.” (Choi 2009) Blevins & Johnsen (2010) stated that their research study is the “first demonstration of spatial vision in an echinoderm sheds further light on the complex optical structures and photobehaviors found in this phylum.” “It appears that sea urchins may use the whole surface of their bodies as a compound eye, and the animals’ spines may shield their bodies from light coming from wide angles to enable them to pick out relatively fine visual detail….Some of the animals may interpret the object as a predator and flee, while others identify it as shelter and head towards it.

Because they are technically animals is irrelevant. What do you think of the answers? The top results of a cursory search for “do mussels have feelings?” were populated with articles by vegans discussing the ethics of eating bivalves, including mussels. At least according to such researchers as Diana Fleischman, the evidence suggests that these bivalves don’t feel pain. These infections … Bivalves have methods of sensing damage (similar to our bodies), but are not sentient, thus do not feel pain, analogous to plants. You’ll see what I mean. Regarding predation, “Bivalves readily utilize chemical exudates that emanate from predators and from injured conspecifics to evaluate predation risk (Caro & Castilla 2004, Cheung et al. As you may have noticed, I’ve taken most of my text from scientific literature. The other thing to consider is If a mother and father dog look very similar to their offspring dog, then why might their offspring be chubbier than them? These might be subtle, so stay vigilant and never be afraid to ask your vet about anything that might signal that your dog is in pain. However, it shows that although oysters have simple, yet efficient nervous system to respond to the type of lifestyle that they live, they also have sensory structures and receptors like those found in other animal species. Or are their movements just muscles automatically contracting due to an outside stimulus? Sweat the onion with Opioid receptors have also been observed and studied in mussels (Aiello 1986; Cadet and Stefano 1999) AND to quote the biggest proponent of bivalve eating in the vegan community, the Sentientist herself, “Many animals have opiate receptors, indicating they are making painkillers and regulating pain within their own nervous system.”. Do mussels feel pain? You feel like your muscles are always tight or strained, sometimes to the point of frequent pain or even chronic pain. Again, these are examples that oysters actively respond to their environment (predation in this case) as any other animal species would when threatened. He further stated that, “Mather (1989) suggests, we should simply accept that these animals ‘are different from us, and wait for more data.’, It would be unreasonable to apply the same guidelines of pain that we apply to ourselves and other vertebrates to species that are completely different to us. When you feel them they may be floppy and a little reduced in bulk. For a meal-sized portion of mussels … Because this is part of a collection of Valentine’s Day essays, here’s perhaps the most important piece: I love oysters, and mussels, too.

Hand pain can be caused by disease or injury affecting any of the structures in the hand, including the bones, muscles, joints, tendons, blood vessels, or connective tissues. (2015), “collectively suggested that CgDOR for [Met(5)]-enkephalin could modulate the haemocyte phagocytic and antibacterial functions through the second messengers Ca(2+) and cAMP, which might be requisite for pathogen elimination and homeostasis maintenance in oyster.” Varga et al.
