Lecanicephaloidea is an order of tapeworms of the subclass Cestoda. Species in the order consist of intestinal parasites of elasmobranch fishes.[1]
Anatomy
The order is distinguished in that the scolex consists of two parts. The lower half forms a neck bearing four small suckers. The upper half is either globular or tentacle-bearing, and shows glandular structures.[2]
