This arboreal, nocturnal frog is rarely observed far from permanent water. Males typically call from leaves covered by other leaves. The call is 2-4 notes, "boop-boop-boop", produced at a rate of 14-40 notes per minute. Clutches of about 840 green eggs, 1.6 mm in diameter are laid in water in forest ponds. Tadpoles are slender with a total length of about 30 mm. The body is wider than deep with a broad snout; the eyes are large, almost dorsal but directed laterally.

Status:
Uncommon. In the Reserva Comunal Tamshiyacu-Tahuayo area it is found in flooded forest along the Tahuayo River, and blackwater lakes in the Amazon-Tahuayo floodplain.
