This Philippine nudibranch is characterized by a prominent gill plume, camouflaged drab
appearance, knotty pustules and green broccoli-like clustered tubercules along its mantle.
I have listed this as an unknown nudibranch for some time. Recently Erwin Kohler,
proprietor of the fine Mediterranean Slug
Site, listed this as Dendrodoris
tuberculosa (family Dendrodorididae) after consulting with a
colleague (I am retaining the page name in order to preserve external links).
Here are some other links to photos or illustrations of Dendrodoris
tuberculosa, with some from some extraordinary web seaslug
Bolland's slug site, the Australian
Museum's Sea Slug Forum, and Mike
Miller's slug site:
