Are there mole rats that can't feel pain?

Answer 1

All naked mole rats can feel some sort of pain, but not the way humans do. They will feel pain if pricked by a needle, for example, but they will not react to acids or capsaicin (the stuff that makes chili peppers spicy). You could pour lemon juice on one of their cuts and they wouldn't flinch a muscle.

I'm sure there are some naked mole rats out there who cannot feel any pain at all, but this would only be a genetic error.

The reason for this may be that they live in carbon dioxide rich enviornments, which is harsh on the skin. It is likely an evolutionary adaption that they cannot feel this burning sensation. Search up 'Can Naked Mole Rats Feel Pain?' on Google if you want the whole scientific explanation.
