Do worms feel pain

Pain in invertebrates is a contentious issue. Although there are numerous definitions of painalmost all involve two key components. First, nociception is required.

A web site for fans of earthworms tackled the question recently:. They do not anticipate pain or feel pain as an emotional response, however. They simply move in response to pain as a reflex response. Possibly in line with the growing support for panpsychism in science, University of Washington evolutionary psychology professor David P. Barash, asks us to consider that worms do indeed feel pain in a deeper sense than an automatic response:.

Possibly in line with the growing support for panpsychism in science, University of Washington evolutionary psychology professor David P. Barash asks us to consider that worms do indeed feel pain in a deeper sense than an automatic response:. I vividly recall, as a child, watching with horror as my uncle threaded a worm on a hook. Barash, author of many books including Through a Glass Brightly: Using Science to See Our Species as We Really Are , alludes to a growing awareness that our traditional evolutionary assumptions about sentience may not be correct:. Who feels more pain, a person or a cat? A cat or a cockroach? But what if our intuition is wrong and the opposite is true? Perhaps animals that are less intelligent feel not only as much pain but even more. A correlate of this attitude, rarely challenged even today, is that the more similar animals are to us, the more likely they are to feel pain. I want to take issue with this and suggest a counterintuitive hypothesis: That animals with less cognitive capacity might feel at least as much and perhaps more pain than their smarter cousins.

Do worms feel pain

Worms can actually feel all kinds of things, but whether worms feel pain is actually up for debate in the scientific literature with more studies leaning towards the conclusion that yes, worms do feel pain. For example, it is known that worms react to various types of stimulation. These include sensitivity to light, extreme temperatures and moisture.

When it comes to the most basic and adaptive traits, we are all cut from the same underlying cloth. Hope this helps! The ability to experience nociception has been subject to natural selection and offers the advantage of reducing further harm to the organism. Nociceptors have been identified in a wide range of invertebrate species, including annelids , molluscs , nematodes and arthropods. Tent caterpillars? The strike may function to dislodge small attackers and startle larger predators. Learning to avoid a noxious stimulus indicates that prior experience of the stimulus is remembered by the animal and appropriate action taken in the future to avoid or reduce potential damage.
