(Porch, pg455) | Class Cestoda, commonly known as tapeworms consists of long(6m or 20 ft.), soft-bodied, legless invertebrate with bilateral symmetry. They have a primitive nervous system but have the characteristic of [[cephalization]](having all the sensory organs concentrated in the anterior or head region). They develope from three cell layers(from outside to inside): epidermis, mesoderm, and the gastroderm, with a thick tegument protecting them from the host's digestive jucies. Also they spend their entire adult life inside the small intestine of a vertebrate. They live in the small intestine because they have no digestive system of their own and thus must rely on absorbtion of already digested nutients.(Porch, pg455) | ||
