Lecanicephaloidea is an order of tapeworms of the subclass Cestoda. Species in the order consist of intestinal parasites of elasmobranch fishes.[1]
Anatomy
[edit | edit source]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] The anatomy of the order is similar to that of the Proteocephaloidea.
