Peltodoris lentiginosa (Millen, 1982)
Common name(s): Giant freckled dorid
|Synonyms: Anisodoris lentiginosa|
|Peltodoris lentiginosa collected from about 20 m depth, Sares Head|
|Dave Cowles, July 2006|
How to Distinguish from Similar Species: The large size and numerous large blotches make this dorid distinctive.
Geographical Range: Kodiak Island, Alaska to Capa Arago, Oregon
Depth Range: Intertidal (mostly subtidal) to 33 m depth
Biology/Natural History: Feeds on yellow encrusting sponges. Recent evidence (Chu and Leys 2012) also shows that this nudibranch feeds on deep-living glass sponges such as Aphrocallistes vastus and Heterochone calyx, as well as the demosponge Desmacella austini that encrusts them. These are all found in deep sponge reefs (>200 m depth) off the west coast of Canada. This is the first documented instance of animals feeding on glass sponges outside of Antarctic waters.
