|General Biology Additional Information||Little information on the biology of this species was found. However, a detailed description of its anatomy is given by Fordham (1925).
Mettam (1971) suggested that the wide body shape of Aphrodite aculeata was an adaptation to the 'slow crawling' mechanism of locomotion found in other polychaetes. Forward propulsion is achieved by movement of individual parapodia in a 'fast stepping pattern' rather than the sinusoidal undulations characteristic of many other polychaete worms. For an illustration and detail of the musculature and mechanism involved see Mettam (1971).
