An undescribed species.Comment from Richard Willan on photo #25800
It is not Aldisa pikokai (which is endemic to Hawaii) because it does not have any raised ridges or white radial streaks on the mantle.Comment from Scott Johnson on photo #20710
This is indeed an Aldisa, but I do not think it yet has a specific name. Probably Aldisa sp. would be best for this one. Comment from Nathalie Yonow on photo #8703
This is the Red Sea Aldisa (or Paradoris), the phyllidiid mimic.Comment from Nathalie Yonow on photo #8707
This is either Aldisa sp. or paradoris sp. It mimics phyllidiids and you can just see the gills at the back! Comment from Richard Willan on photo #7497
This is not Aldisa pikokai because that species has 3 central ‘pits’ that are much smaller in size, and there are reticulate ridges on the flanks of the mantle.Comment from Richard Willan on photo #881
