Bugs and Pain

Bugs may be a pain to us, but they feel no pain. Pain is officially defined as, "An unpleasant sensory and emotional experience associated with actual or potential tissue damage". It is experienced differently by each person and organism. Because of this it is extremely difficult to describe just how an animal experiences pain.

To study how an animal experiences pain, argument-by-analogy is applied. This means if the animal reacts in a similar way to how we would, we believe they are experiencing pain. An example might be if a dog is pricked with a pin and runs away, as a human would.

Insects have no capacity to feel pain. Nociceptors are what carry the feeling of pain to the brain. These are essential to experience pain, yet insects and crustaceans have never been found to have any nociceptors. This means most of these animals are unable to feel any sort of pain. Most insects do not possess nociceptors. I knew when I squished them they were not yelling.
