Yes, snails are believed to be capable of feeling pain, though perhaps not in the same way humans do.
While snails lack a complex brain structure like mammals, they possess associative learning abilities. This suggests a level of sentience that allows them to experience both pleasure and pain. The capacity for associative thinking, even in a primitive form, indicates that snails can learn from experiences and react accordingly, which points towards the ability to perceive and respond to painful stimuli.
In summary, the evidence, although indirect, suggests that snails do indeed experience pain as sentient beings.
