Beautiful blue Dirona albolineata

While trying to find a small predatory sea star, Ailey, Bader & I found this beautiful blue sea slug (Dirona albolineata) on a net hanging off the Pearson College dock. I have never seen a blue one before – anyone else??

The blueness shows up best in the photo below where the nudibranch is in a small tub with juvenile pipefish, two shrimp (one shrimp was also very blue) and a clown nudibranch (Triopha catalinae) which we also found on the dock.

I’d love to hear any ideas about why it might be blue…
