Oysters and Kingdom Animalia
At face value, this issue may seem open and shut. Oysters are bivalves and come from the kingdom of Animalia. Some argue that oysters are more closely related to plants than animals, but from a scientific perspective, that is not the case no matter how sedentary they may be. With that in mind, we come back to the traditional definition of veganism, i.e., the non-consumption of animals and animal-derived products. If we stop here, then sure enough, we can argue that oysters are in fact, not vegan. There have been growing schools of thought on the topic for a decade, so let’s talk a bit about the counter-arguments for vegan oyster consumption.
Do Oysters Feel Pain?
It has been argued that because oysters do not have a central nervous system, they are unlikely to experience pain, at least in the same way humans or other animals do. Even when injured, an oyster does not move. Ethicist Peter Singer had written in early editions of his book Animal Liberation that oyster-eating was sanctioned in the vegan diet only to redact that statement later. His reasoning was, of course, “Because we cannot say with confidence that these creatures do feel pain, you can have equally similar confidence in that they do not feel pain.” With this same argument, one could argue that because we cannot understand forms of pain in plants that they do, or do not feel pain. However, we still eat vegetables, leafy greens, and legumes, etc. Some people come to veganism from the realm of compassion for animals, so if oysters do not have a face, do not feel or react to what we understand as pain, and can be farmed sustainably
