Source-derived summary

The toothless catfish (Anodontiglanis dahli) is a species of catfish (order Siluriformes) of the family Plotosidae. This fish originates from northern Australia, including Fitzroy, Daly, East Alligator, Roper, Mitchell, and Archer Rivers, in lentic and lotic freshwater habitats. It grows up to about 40 centimetres (16 in) TL.

The toothless catfish lives in clear, flowing waters. It has been reported to be solitary, but it also often forms aggregations around log snags or in deeper rock pools. It also occurs in sandy bottoms around the cover of woody debris and in flooded lagoons. This fish feeds on aquatic insects, mollusks, prawns, and bottom detritus by thrusting its snout into the sandy bottom. Nothing is specifically known about the breeding biology, but it probably spawns early in the wet season. This fish most definitely does have teeth (in its pharynx).

Editorial summary

“Toothless catfish” enters the record as species of fish. Crown Archives preserves that source wording while asking what Toothless, catfish and species can confirm, complicate or overturn.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current 139-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 strongest next move is a source search built around Toothless, catfish and species.
Editorial analysis

Why this record matters

“Toothless catfish” is worth following because a concise public description often conceals a longer documentary argument. Here, Toothless, catfish and species provides the most credible route into that argument.

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 Aug 16, 2026. The linked authority identifier is Q3752827. 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
