Big Pink Worm is an Immature Earthworm

“Are these earthworms?” asks Adam in his submission regarding the big, pink worm pictured below. Now, he refers to a multitude of worms, but only pictures one, but we assume that the other worms look like this one. And to answer his question, we do think that this is an earthworm. Its coloration, segmentation, and shape point to this conclusion. The one thing it is missing is the clitellum, a physical trait which is characteristic of earthworms. The clitellum is the band of thicker skin that encircles the worm’s body, usually near its head, sometimes near its center. It is usually a different color from the rest of its body.
