If you love Nudbranch, I suggest you to go to this page http://www.nudipixel.net because they can give you a very very detail information about Nudi. I think by far they have the most complete collections based on genus where you can identify your Nudi, plus you can search based on location. AWESOME!
So, this is my second batch of Nudi photo collections. Basically for my remembrance so one day I can say “Yo, grandkids, granny took picture of Nudi, whatcha doin with your youth eh?”
