Eli5: do fish feel pain?

714 views

If so: how do they handle those parasites that consume their tongues without dying from the pain? They have no appendages, fingers, or other means to remove the parasite so how to they not just succumb from the excruciating pain? (Also, how does that bug parasite thing then survive in their mouth?)

Lots of confusion here!

We don’t really know. Pain is a difficult thing to measure. Especially in something you have no ability to communicate with. The general consensus is yes, probably, but not in the same way that we do.
