Recently, one of our reader’s in Alabama sent in this picture of a tiny worm she found on her desk that her cat sleeps on. She found four of the same type in one day, which appear to be translucent in color, with a black stripe on the inside that runs the length of their bodies. In comparison to the strands of hair on the picture, this worm is minuscule in size.

A reader sent an excellent picture of a transparent worm on a beach in Thailand. Technically, the worm isn’t really transparent because you can’t simply see directly through it to the objects behind it, perhaps in part because it is faintly red, so we suppose it is more like a translucent worm, one whose skin is not a solid color, but definitely isn’t entirely see-through either. The reader was first of all wondering if she had found a worm at all, and if so, she asked us to identify exactly what kind it is. What type of translucent red worm might be found on a beach in Thailand?
