As Veganism grows, many people have begun to argue whether or not Oysters should be classed as vegan-friendly. As we have discussed above, Oysters do not feel any pain. This is down to the fact that they do not have a central nervous system.
Due to this, they do not have a brain or any type of neuron processing hub, which means that they do not feel any pain at all. Even when pearl farmers open the oysters, the mollusk feels no pain.
That being said, once the mollusk is fully open it will not survive for long. If you ever see an open oyster, the mollusk has already been killed.
Now, some people feel strongly that due to this inability to feel the pain that oysters can be eaten by vegans. However, PETA has confirmed that as Oysters belong to the animal kingdom that they are not suitable for vegan consumption.
