Figure 2. A–F, faecal pellet analysis of Neopolynoe chondrocladiae from station CS-BT6 (specimen ID CS-BT6-602-B2, light microscopy). A, general view of the polynoid; white arrow indicates the faecal pellet. B, general view of the pellet. C, detail of a pereipod fragment (possibly from the isopod genus Astacilla) within the pellet. D, detail of an appendage of an unidentified crustacean within the pellet. E, aggregation of microsclere isochaelae (white arrow) and scattered anchorate isochaelae (black arrow) within the pellet. F, detail of anchorate isochaela (black arrow in E). G, H, SEM micrographs of a fragment of Chondrocladia robertballardi (specimen ID CS-ECOMARG). G, calanoid copepod (possibly genus Calanus) attached to the anterior part to the axis of C. robertballardi. H, detail of one of the appendages of the copepod surrounded by isochaelae (white arrows).
