Source-derived summary

Amphiarius rugispinis, the softhead sea catfish, is a species of sea catfish which is found along the northern coast of South America. It is found chiefly in turbid waters of estuaries and around river mouths; it originates from brackish and marine waters of Trinidad and Tobago, Guyana, Suriname, French Guiana, and Brazil. This species grows to about 45 cm (18 in) TL. Reproduction in A. rugispinis appears to be between September and November. The diameter of the eggs is 14–15 millimetres (9⁄16 in), numbering about 30–35 per female.

Editorial summary

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

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current lead gives the account dated anchors—2011—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where Amphiarius, rugispinis 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 fish. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Sep 30, 2025. The linked authority identifier is Q2022051. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2011.

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.
