Distribution of Diaulula sandiegensis in British Columbia
Details about map content are available here.


The nudibranch Diaulula sandiegensis has been split via morphology and genetics into two species that overlap in southern BC. The northern species is the spotted or leopard nudibranch, Diaulula odonoghuei (Steinberg. 1963). It is the common species found intertidally. True Diaulula sandiegensis is called the ringed dorid and is almost exclusively subtidal in the northern portion of its range. The maps for both species show the same distribution because the databases are not yet updated.
