Cruziohyla craspedopus – AKA Fringed leaf frog or Fringed tree frog – is a Phyllomedusid family member…found in the Amazonian lowland rainforest. Spending their time in the high canopy, they only come down to the lower branches or ground to breed.

This is a rare species of frog through presently not of great concern yet with conservationists lest imminent habitat loss is realized.

Cruziohyla craspedopus, the fringed leaf frog[1][2] or fringed tree frog,[3] is a species of frog in the family Phyllomedusidae,[1][2][3] alternatively treated as the subfamily Phyllomedusinae of the family Hylidae.[4] It is found in the Amazonian lowlands in Brazil, Colombia, Ecuador, and Peru, and possibly in Bolivia.[2]


Adult males measure 53–66 mm (2.1–2.6 in) and adult females 68–76 mm (2.7–3.0 in) in snout–vent length. The head is slightly wider than it is long. The snout is sharply truncate in lateral view. The fingers and toes are webbed. The hind margin of the tarsus bear extensive dermal appendages forming irregular spurs. The dorsum has uniform dark green dorsal background coloration interspersed with irregular-shaped large pale blue-grey lichenose blotches. The flanks have narrow black lines. The undersides and concealed surfaces of the flanks and legs are yellow.[3]

Habitat and conservation

Cruziohyla craspedopus is a high-canopy frog of primary tropical lowland rainforest at elevations of 50–600 m (160–1,970 ft) above sea level. It only descends to lower branches for breeding, which takes place in fallen trees holding small water pools. However, tadpoles have also been found in small pools on the ground.[1]

Cruziohyla craspedopus is a rare species. It is not facing major threats, but it can locally suffer from habitat loss caused by human activities (e.g., agriculture). It occurs in several protected areas such as the Yasuni National Park in Ecuador and the Manú National Park in Peru.[1]
