scolex of Diphyllobothrium latum. This is a pseudophyllidean tapeworm and
has "sucking slits" called bothria rather than suckers or acetabula as in the
cyclophyllideans. The scolex is also unarmed or without a hooked rostellum.
This tapeworm is often called the broad or fish tapeworm. Freshwater fish
are the second intermediate host.
