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.

Members of Notocomplana are known to prey on limpets (Phillips & Chiarappa, 1980. JEMBE 47:179-189)
| 
Lasaea sp., is a tiny brooding hermaphroditic asexually-reproducing (parthenogenic) bivalve with the highest ploidy levels known for any mollusc.
| 
Lasaea sp. has two widespread clones along the West Coast, partly distinguishable by color (O'Foighil & Eernisse, 1987 - pdf)
