Source-derived summary

Rostanga elandsia, is a species of dorid nudibranch. It is a marine gastropod mollusc in the family Discodorididae.

Distribution

This species has so far only been found around the southern African coast from the Atlantic side of the Cape Peninsula to the eastern side of False Bay. It has been found from the mid-intertidal zone to at least 30 m. It is endemic to South Africa.

Description

The red sponge nudibranch is a yellow-orange to red dorid with scattered small black spots on its notum. It is extremely well camouflaged on its prey sponges. Its gills are arranged around the anus and its rhinophores are perfoliate. It may reach a total length of 30 mm.

Ecology

This species feeds on red and yellow-orange sponges which determine the animal's colour.

Editorial summary

The public source identifies “Rostanga elandsia” as species of mollusc. This brief keeps that definition visible, then builds a research path around Rostanga, elandsia and species.

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current 129-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Rostanga, elandsia and species providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Rostanga elandsia”, the useful work is to connect “species of mollusc” to the records capable of establishing context and consequence.

Evidence profile

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 19, 2026. The linked authority identifier is Q7305391. None of the 0 selected statements returned an explicit reference.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
