NettetBelow the large oval section lies an alliptical and almost solid structure the posterior sucker, which is lined with a thin epidermis, circular and longitudinal muscles and is filled with numerous round and irregular sucker glands. ADVERTISEMENTS: 4. The botroidal tissue and dermal layers are absent in posterior sucker. NettetThe protrusion of the suckers is dependent upon the isotonic contraction of the body muscles.
