Litobothriidea [Litobothriidea]
Description
Litobothriidea is a relatively small order of tapeworms, primarily found in cartilaginous fish such as sharks. These parasites are characterized by their long, ribbon-like bodies and a scolex that adheres to the host's intestinal wall. They are unique among tapeworms for their minimal segmentation and the presence of microtriches that cover their surface, aiding in nutrient absorption from the host.
