Big Nudibranch

 

 I found myself face to face with the largest Nudibranch I've ever encountered this morning. It was at least four inches across and perhaps as much as seven inches. It was also very cooperative in that it posed quietly for my camera.

And I never would have noticed it at all if it hadn't been pointed out to me by one of Maui's very own, very real Mermaids. Thanks Peemer.
