An inconspicuous, very common flatworm that reveals itself to be quite stunning on close examination. In the field, their brilliant pink and white margin and gold-spotted papillae aren’t quite as noticeable as when seen through the microscopic lens of a camera. John Hoover’s Flatworm page provides some more photos and detailed taxonomic history. The images below are of a juvenile Thysanozoon tentaculum (we’re pretty sure). From one angle, its papillae take on a spindle-like shape, but this is likely just due to the perspective provided by the camera.
