==Description==

''Doris odhneri'' is the largest nudibranch on the California coast, measuring up to 20 cm. It is completely white in color with no markings, however anomalies with a yellowish hue have been described in the Puget Sound region. A conspicuous characteristic of this nudibranch is its gill. It is composed of seven fluffy plumes and its [[rhinophores]] have 20 to 24 [[lamella (zoology)|lamellae]].<ref name="Behrens 1991"/><ref>Rudman, W.B., 2000 (October 12) [http://www.seaslugforum.net/factsheet/archodhn ''Archidoris odhneri'' (MacFarland, 1966).] <nowiki>[In]</nowiki> Sea Slug Forum.

==Life habits==
Their diet consists of sponges, mostly ''[[Halichondria]].''<ref>Kozloff E. (1993). ''Seashore life of the Northern Pacific Coast''. University Press.</ref>
It is rarely found in the [[intertidal]], and is more likely to be found in the [[subtidal]] to 75 ft.
Like most nudibranchs, ''Doris odhneri'' is [[hermaphroditic]] and mates with the right sides of the body together. Elegant ribbon-like egg masses are laid and attached to hard substrates.<ref>Hildering, J. & Miller, G., 2007 (Jul 27) [http://www.seaslugforum.net/find/20168 Doris odhneri eggs?.] <nowiki>[Message in]</nowiki> Sea Slug Forum.

==Distribution==
''Doris odheri'' can be found from Kenai Peninsula, Alaska to Point Loma, California.<ref name="Behrens 1991"/> They have also been discovered in Korea.<ref>{{Cite journal |last=Jung |first=Daewui |last2=Lee |first2=Jongrak |last3=Kim |first3=Chang-Bae |date=2013-04-30 |title=New Records of Four Doridoidean Nudibranchs from Korea |url=http://koreascience.or.kr/journal/view.jsp?kj=DMBRBT&py=2013&vnc=v29n2&sp=191 |journal=Animal Systematics, Evolution and Diversity |language=en |volume=29 |issue=2 |pages=191–197 |doi=10.5635/ASED.2013.29.2.191 |issn=2234-6953|doi-access=free }}</ref>
