Representative shell and radula morphology of vent/seep pectinodontids. (a–c) Bathyacmaea nipponica, Off Hatsushima seep. (d,e) Bathyacmaea secunda, Iheya North Knoll vent. (f) Bathyacmaea tertia, Iheya North Knoll vent. (g,h) Bathyacmaea cf. tertia, Jiaolong Ridge seep. (i) Serradonta vestimentifericola, Off Hatsushima seep. (j,k) Bathyacmaea nipponica translocated from mussels to worm tubes. (l) Serradonta vestimentifericola translocated from worm tubes to mussels. Scale bars, left (shell) = 2 mm; right (radula) = 100 µm. Arrowheads indicate the start of shell deposition during translocation.
