“Can you help identify this worm/creature?” writes this reader about the brown, worm-looking critter pictured below. “They are out by the seeming hundreds right now and seem to have a tapered body. It’s raining, 55 degrees. Northwest Arkansas. Pictures attached.” Immediately, we have to say that the photos that our reader sent in were quite blurry, even without zooming in on the photo. This means that when we did zoom in for a better look at the worm, we could not see any of the finer details of the worm’s physical characteristics. For that reason, we will unfortunately not be able to identify the creature with 100% certainty or accuracy.

“I find hundreds of earthworms in my pool after it has rained”, writes this reader in their submission, which does not include any pictures or videos. “It looks like a mass suicide? Now, I read they can survive for up to two weeks under water. Is the chlorine in the pool toxic for them, and how can I help them get back into the ground?” To start with, whether or not earthworms can survive underwater for two weeks seems to be a debatable topic. Some sources say they can survive for weeks underwater, while others say they can survive for hours. Our take is that this would be entirely dependent on the species. There are species of earthworms that belong to a group of worms called ‘bloodworms’. They are typically red in color, which they get from the excess production of hemoglobin, which does indeed allow them to survive in low oxygen conditions, such as underwater, for long periods of time. That said, not all species of earthworms are bloodworms, and we doubt the earthworms our reader found are bloodworms.
