Scinax exiguus

Scinax exiguus is a small treefrog of the family Hylidae, sometimes called the Gran Sabana snouted treefrog. It is found in the Gran Sabana of Venezuela and in the Roraima state of the adjacent northern Brazil, reaching as far south as Boa Vista. Adult males measure 18 to 23 millimeters and adult females 20 to 25 millimeters in snout to vent length. The body is slender, the head is much longer than it is wide, and the snout is pointed. The coloration changes with the time of day: at night the back is pale yellowish tan with darker tan markings and cream stripes along the sides, while by day it turns brown with dark brown stripes on the body and bars across the limbs. Males have a yellow vocal sac. The frog lives in the margins of wetlands, marshes and slow-flowing streams at elevations of about 500 to 1,500 meters. Males call from grasses, a pair in amplexus has been found in a bush about one meter above the water, and the tadpoles develop in shallow pools. It is a common species that is not facing significant threats, and it might occur in Canaima National Park.
