L. rugatus
| 
Eernisse et al. (1988; Veliger 30: 244-247) found tissue hemoglobins in the foot and gills of L. rugatus; the only chiton known to have these.
| 
L. rugatus |
L. rugatus often has its posterior girdle distended like wings.
| 
The girdle is extended near valve seven. When viewed from underneath, it appeared that this posture might enhance circulation past the gills, which form a continuous posterior semicircle in this chiton lineage.
