Lastly, if you still can not find it,
submit your nudibranch photos with detail information about it, we would be glad to help you identifying it by sending the pictures to some nudibranch experts. Please note that by submitting you also give us the permission to publish your photo in Nudi Pixel (we keep the copyright notice to you, though). And if it doesn't meet our quality, we could NOT identify and publish it.
