Hymenolepis nana (Cestode) –Parasite
H.nana adult tapeworms are quite small, measuring 2.5 – 4.0 cm in length. The tiny, knob-like scolex has four suckers and a rostellum bearing a ring of 20 - 30 hooklets. Proglottids (segments) are wider than they are long.
Sorry, I have no worm to take a photo of, however they can be found elsewhere on the web.
