Description:
Males
66-85 mm., females 76-103 mm. The skin on the dorsum is smooth
in females and bears large, spinous tubercles in males; in large
individuals, the skin on the top of the head is fused with the
underlying bones, which form a pair of longitudinal ridges between
the eyes. The snout is bluntly rounded, and the head is nearly
as wide as it is long. The tympanum is 3/4 the size of the eye.
The dorsum is tan to reddish brown with dark irregular markings
on the back and transverse bars on the limbs. The flanks are tan
to creamy white with dark brown spots. The venter is cream, usually
with brown spots or mottling on the chest. The iris is greenish-bronze
with radiating black lines.
Ecology
Habitat:
arboreal , found in terre firme forest, secondary
forest and clearings.
Niche:
carnivorous: prey includes insects and any small creatures it
can catch.
Life History:
At night, this large treefrog is usually seen perched crosswise
on the trunks of small trees and vines in primary and secondary
forest. After heavy rains, breeding takes place in temporary ponds,
where males usually call while floating on the surface of the
water. The call is a loud 'boop-boop-boop", followed by a
"worrr". Small haevily pigmented eggs are deposited
as a film on the surface of the water.
Status:
Uncommon. In the Reserva Comunal Tamshiyacu-Tahuayo area it is
found in primary forest along the Quebrada Blanco.
