The Apalachicola waterdog (Necturus moleri) is a species of aquatic salamander in the family Proteidae.

[1][2] It was formerly thought to be a lineage of the Gulf Coast waterdog (N. beyeri), but a 2020 analysis found sufficient morphological and genetic divergence for it to be considered its own species, and it was thus described as its own species, N. moleri (alongside the Escambia waterdog, N. mounti).

[3] It is found in southeastern Alabama, the Panhandle of Florida, and southwestern to north-central Georgia.

It is found in the Apalachicola, Chipola, Choctawhatchee/Pea, Econfina, and Ochlockonee river basins.

It shares these phenotypic traits with N. mounti, although it is genetically distinct.
