We found these two tiny nudibranchs on our local beach this afternoon, washed up with a heap of bluebottles (Portuguese Man'O'War). Each is under a centimetre long, probably closer to 7-8mm. We scooped them up in a shell for these pics. These little creatures float upside down on the surface tension of the water. They are the only species in the genus Glaucilla, but are closely related to the larger (and showier) Glaucus atlanticus (http://en.wikipedia.org/wiki/Glaucus_atl...). Update 5/10/14 - This species appears to have been reclassified. I have updated the scientific name to Glaucus marginata accordingly.
