Tiny blue nudibranch with a 'wingspan' of under 1cm. The blue colours are actually on the ventral surface, as these creatures float upside down in the ocean using the 'foot' along the centre of their belly to hold the surface tension.
The Pacific Ocean. We found this one washed up on Yaroomba beach.
Not a great deal seems to be known about these tiny sea slugs, except that they eat bits of hydrozoans such as Portuguese Men o' War (blue bottles) and Porpita porpita (blue buttons) and store the stingers in their 'cereta' (the finger-like protusions along the side of their body). I think they're really cute. This series shows one in a variety of poses... in the second one you can see how small it is (check out the grains of sand around it on the surface of the water!) and the fourth one shows it flipped onto its front as the water goes out.

Hi ShannaB, These blue nudibranch photos are amazing! Be terrific to see some of your most recent discoveries here on Project Noah!
I suspected this one was a winner! Well Done, Shanna!
Indeed a beauty..congrats!
Such good shots.. cobgrats.
Thanks Lisa & Christiane!
Congratulation Shanna.. I so hoe I can find one of these one day!
Congrats ShannaB, your beautiful alien-like Blue Nudibranch placed 2nd in the "other" category for the Best of 2015! Here is the link for the '2016 Best Wildlife Photo mission so you can add more fantastic spottings for this year! http://www.projectnoah.org/missions/2004...
Thanks Ashley! Jim, Albert is right - we found these washed up on the beach. We scooped out a hollow in the sand so we could see these guys floating, and I took the photo from above. They are absolutely tiny - in the second shot you can see the grains of sand floating on the surface of the water.
All this time, I have been looking in the wrong places.
@JimNelson, its more likely you will see this Nudibranch at the beach than when scuba diving.
Shanna...I have spent many years diving, and have never seen this one. Underwater macro sometimes takes time and patience. Great job on this one!
Love this little cutie.. :)
