Paul Humann said that the species closely related to the blue streak nudibranch but may be an entirely new species.
Can you please help identify this species of nudibranch.

Luckily I have just received from Paul Humann a copy the Enlarged 2nd Edition of his Reef Creature Identification - Florida Caribbean Bahamas which he has written with Ned Deloach. I will prepare a review to update the existing review when I get a moment.
Armed with this book I can identify what you mean by the 'Blue Streak Nudibranch'. Your animal is in fact the next one down page 305 which Humann & Deloach identify as Flabellina sp. It is Flabellina marcusorum. I have included a close-up of the head alongside to show the papillate rhinophores. This species is known from only a few records so your find is an important addition to our knowledge. Humann & Deloach's photo is from Belize, which is another new record.
