Still frame images of Digit III, the middle toe, of a live Aneides vagrans. Images were taken with the salamander in a neutral posture on a flat surface from (A) dorsal, (B) lateral, and (C) ventral views. These images show the digital sinus and the bifurcated terminal phalanx of a living salamander; the structure of these features was corroborated by our histological preparations, shown in Figures 3 and 4.
