Polyclads are able to achieve a wide range of movements especially while swimming and gliding on surfaces.
(ii) Reproduction - Mating:Penis fencing strategy
Polycladscarry out an interesting mating behaviour known as "penis fencing".Watch the video under "Reproduction".
(iii) Feeding & Nutrition
(iv) Internal Transport System
There are no specialized organs for respiratory functions in polyclads. Gaseous exchange occurs across their entire body surface through diffusion. See "BodyWall".
