Notodoris serenae
species of nudibranch
Notodoris serenae is a species of sea slug. It is a dorid nudibranch, a shell-less marine gastropod mollusc in the family Aegiridae.
Distribution
This species was described from Papua New Guinea. It lives in the Indo-west Pacific area, where it has been found in the Philippines, Indonesia, Malaysia, Palau, Pohnpei, the Solomon Islands and Okinawa.
Description
Notodoris serenae can grow to more than 10 cm in length. It is predominantly grey in colour with raised black tubercles scattered all over the body and raised black ridges on the head and the processes in front of the gills. There are large extra-brachial appendages which shelter the gills, which are green and sometimes edged with yellow. The rhinophores are yellow and so is the underside and edge of the foot.
Diet
Notodoris serenae feeds on calcareous sponges belonging to the family Leucettidae. It has been recorded eating Leucetta chagosensis Dendy, 1913.
Begin with the source’s own compact description: “Notodoris serenae” is species of nudibranch. The dossier treats that line as a proposition to test through Notodoris, serenae and species, not as a finished interpretation.
Why this record matters
The phrase “species of nudibranch” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated May 15, 2026. The linked authority identifier is Q59310675. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1913.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
