Amphiuma pholeter
The one-toed amphiuma (''Amphiuma pholeter'') is an aquatic, eel-like salamander native to the southeastern United States. It was unknown to science until 1950, when it was collected by herpetologist W. T. Neill. It is rarely observed in the wild, and much about the species remains uncertain.
== Description ==
The one-toed amphiuma is considered aquatic, and ranges in coloration from gray-black to purplish-brown. Unlike the other two ''Amphiuma'' species which have distinctively lighter undersides, one-toed amphiumas are the same color on both the dorsum (back) and the venter (belly). It can also be distinguished by its cone-shaped head and toe number -- one-toed amphiumas have one toe on each foot as opposed to the two or three exhibited by other ''Amphiuma'' species. It is the smallest species in the genus ''Amphiuma'' with the average adult size being 8.5 inches (220 mm).
