Hedrick’s robber frog

Description

Its distinctive features are the pronounced constriction in the back of the head (as if the waist were in the back of the head),a shallow furrow along the middle of the back from between the eyes to near the sacral hump,and the short,rounded snout.Other distinguishing but not necessarily exclusive characteristics are: the small eyes,with narrow upper eyelids,the uniformerly granular dorsum,the pair of light,externally concave lines on the back (not too distinct in very dark animals),the blackish throat of males,and the absence of dark streaks along the sides of the snout.The basic dorsal color may be brown or dark gray,almost uniform or with obscure variegation or vermiculations of lighter gray.The males average 32.8 mm in length,while females average 34.6 mm.
