|Description:||This photograph depicted the strobilocercus, or larval stage of an unidentified tapeworm of the order Cyclophyllidea. Families that are members of this order include Dipylidiidae, i.e., cucumber tapeworm and double-pore tapeworm, Hymenolepidadae, Taeniidae, i.e., livestock parasites, and Anoplocephalidae, i.e., horse and ruminant tapeworms.|
The strobilocercus is the larval form, which after hatching, penetrates into an intermediate host’s gut wall, and subsequently developes into the adult worm. After the intermediate host is ingested by the proper final host, the adult parasitic worm is liberated inside the final host. The strobilocercus contains the scolex, or head region with which it attaches to the intestinal lining, the organism’s bladder, and the elongated strobilated, or segmented region.
