Another teensy white dorid!  This one was a mere 1/2 inch — or 13 mm and it was hiding in a hole beneath a ledge.  At first I thought it was another Janna’s Dorid (much more common), but it turns out  “the white gland at the base of the gills looks triangular (as found in O. muricata) rather than round (as found in K. jannae).” Thanks Karin Fletcher! On initial viewing, the tubercles also appear to be more rounded.  Look for these under kelp in winter.  Other similar looking tiny white nudibranchs include the Spiny Hairy Dorid and the Ridge-tailed Dorid.
