With the recent discussion of Flabellina exoptata we noticed you didn't have any examples of this animal from Vanuatu. Here are some images of Flabellina exoptata from our recent trip to Vanuatu to add to your distribution information. These photos were taken on the wreck of the Bonzer and the bright colour in front of this nudibranch is deck paint showing through the growth. Thankyou for your work on the forum, hope these are of interest.

Thanks Leanne & David,
I have included a close-up to show the rather characteristic arrangement of papillae on the rhinophores.

Hi Bill and everyone!
After diving today at Old Woman Island I thought I might share another new species we have found here. I see you don't have any entries for Flabellina exoptata from Australia, so here tiz.

Good to get an Australian example added to the Forum. It is a well-known Australian resident in tropical waters and extends down both the east and west coasts into warm temperate regions.

I thought this contribution may be of interest to the Forum. This Flabellina exoptata may be in the process of, or just finished laying egg ribbons.

There are certainly two aeolid egg ribbons present, and I wouldn't be surprised if they belong to the Flabellina. I have enlarged part of your photo alongside as it also shows the rhinophores rather well.

This little guy was on a hydroid branch feeding while I took the picture. After detail analysis of the picture I have realized that the rhinophores are not on their usual shape, like intermingled to form a single unit. Hope this will be useful for the Abnormalities page.

I have been puzzled by this beautiful little creature for a number of months, and I can't find it on the forum. The closest I can come is Flabellina marcurosum, but he is not supposed to be in our ocean. Please can you help me? The photo was taken by one of my staff members Nicola Orban.

There are not too many records of this species from the western Indian Ocean. It is Flabellina exoptata, which is quite common in the western Pacific and the Malay-Indonesian Archipelago.

Out-sized rhinophores are a good indicator of juveniles, I guess it's just as important for juveniles to smell (and find) their food as it is for adults, so I guess in this case, bigger is better.

I think you are right. I can't see rhinophores of any colour. They are either missing or somehow obscured in the photo.
