IDENTIFICATION RESOURCES

The differences between a number of species belonging to this genus are very subtle. The following characteristics can be used distinguish M. Rufescens from other bivlaves:

  • Light cream coloured shell with darker bands away from the apex of the shell.
  • Ridges on shell are relatively broad compared to other species of trough shells.
  • The interior of the shell is white with purple blotches.
  • Shorter and more stout than surf clams.
