| Scolex | The "head" of a tapeworm |
| Acetabulum | One of four suckers on the anterior end of a true tapeworm; used to hold onto the lining of the small intestine |
| Tegument | Body wall of a helminth |
| Rostellum | Holdfast organ on the anterior end of an armed trip tapeworm; has backward-facing hooks used to anchor the tapeworm to the wall of the host's gut |
| Armed Tapeworm | True tapeworm that possesses a rostellum on its anterior end |
| Unarmed Tapeworm | True tapeworm that lacks a rostellum on its anterior end |
| Strobila | Body of the tapeworm composed of individual proglottids (immature, mature, and gravid) |
| Hermaphroditic | Having complete sets of both male and female reproductive organs |
| Hexacanth Embryos | Type of tapeworm egg containing a six-toothed embryo (an embryo that contains six hooklets) |
| Metacestode | Larval tapeworm found within the intermediate host; types include cysticercoid, cysticercus, coenurus, hydatid, tetrathyridium, procercoid, plerocercoid, and sparganum |
| Bothria | Two slitlike holdfast organs on the anterior end of a pseudotapeworm |
| Coracidium | Ciliated hexacanth embryo unique to the pseudotapeworms |
| Copepod | An aquatic crustacean |
| Procercoid | Type of metacestode stage unique to the pseudotapeworms; found within the first intermediate host, usually a tiny aquatic crustacean |
| Plerocercoid | Type of metacestode stage unique to the pseudotapeworms; the stage where the pseudotapeworm becomes infective for the definitive host and is found within a second intermediate host (usually a fish) |
| Psocids | Primitive insects often associated with vegetation |
