Nerilla antennata has nine segments with chaetae and a prostomium with two very large clavate palpates and three segmented tentacles. On the prostomium it has four eyes and two ciliated nuchal organs on the side. The other segments have both dorsally – and ventrally parapods with simple chaetae. The peristomium has two segmented anal cirri.

Male specimens can be identified by three pairs of gonoducts at segment 6 - 8. Females have ovaries at segment 6 and oviducts at segment 7. [1][2]
