               Dr. David Menton: Yes, so I became interested in comparing them
               myself. I had a laboratory technician at the time who had a pet boa con-
               strictor, so I took a look at some of its scales from shed skin. I was
               amused that they were, of course, not even the slightest bit similar to
               feathers, as these photographs show. The only similarity is that they are
               both made of the protein keratin—like hair, nails and our skin. It’s
               quite different. The most fundamental difference is that the feather
               grows out of a follicle, a tubular down-growth of the epidermis that
               protrudes deeply into the skin, all the way down to underlying bone in
               the case of primary feathers. And this tube of specialized living skin

          (4) The vane sheath develops as a temporary structure that protects the feather growing in
          the outermost epidermal layer. At this point, the epidermal layer divides into a series that will
          later constitute the feather barbs.
          (5) Until the quill extension appears in a pennacious feather, the barbs grow in a spiral form
          around the ring.
          (6) The feathers emerges from the sheaths so long as growth continues. The feather then
          unfolds its curves in order to assume its flattened form. When the feather achieves its ulti-
          mate dimensions, the follicle ring forms a simple tubular stalk at the root of the feather.
