“What type of worm/parasite is this?” is all this reader writes in her submission regarding the white and red organism pictured below. From the looks of it, if this were a worm, it would be a pretty mangled one. It has lost the uniform, long shape that a worm possesses, and looks like a blob of tissue. For that reason, as well as due to the lack of context, we will have to say that the identity of this worm is inconclusive. We would not even be able to guess based on the coloration, as it is uncertain if the red color was actually a part of the worm originally, or if it is blood from its mangled body.
