Pale Rocket Frog

Anomaloglossus blanci is a small frog measuring 15.9–18.8 mm (0.63–0.74 in) long in males and 17.9 mm (0.70 in) in females. Adult males have brownish to reddish-brown back with dark brown splotches and dark brown to light grey flanks. There is a black stripe running down the sides from the snout to the flanks. The underside is tricolored, with black on the throat, blue-and-white-flecked grey upper bellies, and orange on the underside of the limbs and the remainder of the belly. Males seem to have more intense colors while vocalizing to attract male and become duller while raising tadpoles.

This frog lives in rocky and sandy streams, often near larger tributaries, in French Guiana. Scientists observed it between 50 and 200 meters above sea level. Scientists note that the frog lives in one protected place: Parc Amazonien de Guyane. The males sit near streams and call to the female frogs, with activity greatest after dawn and near dusk. After the eggs hatch, the male frogs carry the tadpoles to streams. Tadpoles require parental care to complete maturing after hatching and die within hours if they are removed from the male's back. The species raises one to four tadpoles at once, although it can mate again while raising a clutch of tadpoles.
