Above: Goniodoridella savignyi – Variation in presentation of yellow pigment.

A composite image of four different specimens of Goniodoridella savignyi all photographed at East Boulders, Mudjimba Island on 24/11/2022 – all approximately 6 mm in length.

It is interesting to note the variation in presentation related to yellow pigmentation. The intensity of yellow varies. Some have yellow to gill tips and extrabranchial processes, others do not. Some have a strong continuous band of yellow to mantle margin while in others it is broken and restricted to the pustules on the notal brim. Some have more distinctive and prominent velar tentacles. Some, not all, have a yellow tip to the tail. All have yellow tips to rhinophores and a yellow mid-dorsal streak.
