Source-derived summary

Polypterus congicus, the Congo bichir, is a species of bichir with a maximum recorded size of 970 millimetres (38 in). The colour also varies from yellowish brown to grey, darker in the top, paler in the ventral area. It has a pattern of around 8 irregular vertical bands along the flanks of the fish, that do not extend completely onto the ventral surface. The lower jaw is prominent, much like Polypterus endlicherii. The male has a wider and thicker anal fin. These fish are commonly sold as pets.

Editorial summary

This brief starts where responsible research should: with the source description of “Polypterus congicus” as species of fish. 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 88-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. The account is most persuasive where Polypterus, congicus 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 Jul 27, 2026. The linked authority identifier is Q7226872. None of the 0 selected statements returned an explicit reference.

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.
