Cambeva guaraquessaba
species of fish

Cambeva guaraquessaba is a species of freshwater ray-finned fish belonging to the family Trichomycteridae, the pencil and parasitic catfishes. This catfish is presently only known from Rio Bracinho, a small isolated river in Paraná state, Brazil.
This is an elongate catfish up to 9.2 centimetres (3.6 in) standard length. It has no unique morphological features and can be distinguished from its congeners by a combination of characters including a uniformly grey colouring with only small dark spots on the flank, pelvic fin not covering the urogenital opening and square-ended caudal fin.
This brief starts where responsible research should: with the source description of “Cambeva guaraquessaba” as species of fish. Everything that follows is an evidence route, not borrowed authority.
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.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated May 21, 2026. The linked authority identifier is Q3753721. None of the 0 selected statements returned an explicit reference.
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.
