Roundworms (Ascaridida) are an order of nematodes . Their representatives live parasitically in the intestines of vertebrates and have a spindle-shaped body with a length of up to 50 cm. The mouth opening has three papilla-bearing lips. The esophagus is cylindrical or club-shaped and can have appendages. In some taxa the intestine also has appendages in the initial area. Caudal wings are not developed or at most only indicated.
