This specimen is a combination of the orange and the blue/green variant.
This species was placed by many authors in the genus Siraius Er. Marcus, 1955, which Valdés (2002) synonymized with Doris Linnaeus, 1758.
Doris immonda is at many websites and uw-guides under the names:
Doris nucleola Pease, 1860 or Siraius nucleola (Pease, 1860), let quote Robert F. Bolland: "I've decided that Bill Rudman's message on the Sea Slug Forum (Rudman, 2000) concerning S. immonda provides a credible reason to change the name S. nucleola to that of S. immonda."
There are at the internet pictures of the orange variant from Japan, from Australia, from the Red Sea, and from the Pacific Coast of Mexico , of the green variant from from Australia, and of the blue variant (as S. nucleola) from Hawaii.
