Fringed Leaf Frog
Cruziohyla craspedopus
Rarer than its relative C. calcarifer, this species is a masterpiece of camouflage, featuring prominent jagged skin fringes on its legs that perfectly mimic lichens. Highly prized and delicate.

Species description
Geographical Origin and Habitat: Native to the western Amazon basin, with documented populations in Brazil, Colombia, Peru, and Ecuador. It inhabits the high canopy of primary, undisturbed lowland tropical rainforests. This strictly arboreal species spends its life high in the trees, rarely descending except to breed in rain-filled tree hollows or forest pools.
Taxonomy and Genetics: Belongs to the family Phyllomedusidae, genus Cruziohyla. It has a robust and moderately elongated body, with large adhesive toe pads for climbing slippery lianas. The key taxonomic feature is the presence of jagged dermal flaps (fringes) along the outer margins of the limbs and heels, which disrupt its outline.
Behavior and Habits: Nocturnal and highly arboreal. During the day, it sleeps in a state of torpor, pressed flat against the underside of large, smooth leaves for camouflage. At night, it becomes an active hunter. Breeding males call from water-filled tree cavities, emitting deep, low-frequency guttural croaks to attract females.
Morphology: The dorsal skin is moss green mottled with lichen-like patterns of pale gray or silvery white. The flanks, belly, and inner surfaces of the limbs feature brilliant yellow or orange coloration with vertical black stripes. The large eyes have silvery-gray irises. Mature females are significantly larger than males.
Care, breeding and tankmates
Terrarium Setup: Requires a large, vertically oriented forest terrarium (minimum 60x45x90 cm for a pair). The enclosure must be furnished with sturdy climbing branches, cork bark tubes, and robust live plants with broad leaves (e.g., Monstera, Philodendron) to serve as sleeping spots. A shallow, clean water area is required at the bottom.
Lighting and Heating: Provide moderate lighting with a low-level 5.0 UVB source to prevent Metabolic Bone Disease (MBD). Maintain daytime ambient temperatures between 24°C and 28°C, with a localized basking spot. A nighttime temperature drop to 20-22°C is essential. Never allow temperatures to rise above 30°C.
Humidity and Hydration: Humidity must be kept high (80-90%) by spraying the terrarium nightly with clean, dechlorinated water. Excellent ventilation is critical; the enclosure must have ample mesh areas or fans to facilitate airflow and prevent stagnant air, which leads to fatal bacterial skin infections.
Feeding and Supplementation: Strictly insectivorous. Feed on crickets, roaches (Dubia or Lateralis), and locusts of appropriate size. Dust prey items with pure calcium three times a week and with high-quality multivitamin supplements containing vitamin D3 and preformed vitamin A twice a week.
Compatibility: Peaceful and gregarious, allowing small groups to be housed together in sufficiently large enclosures. However, they must not be cohabited with smaller amphibians (which will be eaten) or other frog species to prevent cross-contamination and stress.
Health and Common Diseases: Highly sensitive to skin toxins, chemicals, and human oils; handling should be avoided unless necessary, and always performed with clean, wet, powder-free gloves. Prone to snout rubbing against glass if stressed, and vulnerable to bacterial infections like red leg syndrome.

The catalog's scalar value is 7.3 cm. The AmphiBIO v1 source reports a maximum adult measurement of 7.3 cm for this species, recorded as snout–vent length (SVL). These figures are not interchangeable: the first is the profile's editorial reference, whereas the second is a published maximum under a specific measurement convention; differences among sources can reflect sex, population, life stage and measuring method.
