Dwarf siren
salamander genus
Dwarf sirens are eel-like salamanders of the genus Pseudobranchus. Dwarf sirens possess external gills throughout adulthood and lack hind legs, and can be distinguished from members of the genus Siren in that dwarf sirens have three toes on each foot rather than four. Whereas sirens have three gill slits, dwarf sirens keep just a single slit. Like sirens, dwarf sirens are restricted to the Southeastern United States.

Why this record matters
The phrase “salamander genus” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 4, 2026. The linked authority identifier is Q1840324. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.
