Source-derived summary

Tochuina gigantea, common name the giant orange tochui, is a species of sea slug, a tritonid nudibranch, a marine gastropod mollusk in the family Tritoniidae.

Bergh (1879) used the name Tritonia tetraquetra in a sense different from Pallas (1788). The valid name for Tochuina tetraquetra sensu Bergh, 1879 is Tritonia gigantea Bergh, 1904. The complicated series of misinterpretations of Pallas' and Bergh's species are explained in a 2020 revision of the family Tritoniidae.

Editorial summary

This brief starts where responsible research should: with the source description of “Tochuina gigantea” as species of mollusc. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current lead gives the account dated anchors—1879, 1788, 1904, 2020—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where Tochuina, gigantea and species can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the science & nature register because the source frames it as species of mollusc. Its deeper value depends on whether names, dates, institutions and citations support that framing.

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 Apr 9, 2026. The linked authority identifier is Q3021578. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1879, 1788, 1904 and 2020.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. 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

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