FIGURE 3 in Redescription of Bathymodiolus septemdierum Hashimoto and Okutani, 1994 (Bivalvia, Mytilida, Mytilidae), a mussel broadly distributed across hydrothermal vent locations in the western Pacific and Indian Oceans

FIGURE 3 Outline sketches of Bathymodiolus septemdierum shells illustrating variability in shape and positions of the anterior retractor and anterior adductor muscle scars. AR: anterior retractor muscle scar; PA: posterior adductor muscle scar; PL: pallial line; AA: anterior adductor scar; LG: ligament. Scale bar is 10 mm and applies to all specimens. A and B: NW Eifuku site, Northwest Pacific; shells are predominantly rounded as in A. C and D: Tu'i Malila site, Lau Basin; shells are predominately angular as in D. E: Kairei site, Central Indian Ridge; redrawn from Hashimoto (2001) holotype. Here, we correct the scale applied to this drawing in the original. The specimen is 55.7 mm long. (A: SIO accession # M19392; B: SIO accession # M19393; C: SIO accession # M19391; D: SIO accession # M19389; E: paratype JAMSTEC #032386).
