Species description
Geographical Origin and Habitat: Widespread in the humid tropical rainforests of Central America, ranging from southern Mexico through Belize, Guatemala, Honduras, Nicaragua, Costa Rica, and Panama to northwestern Colombia. It primarily inhabits the shaded understory, clinging vertically to tree trunks and woody vines.
Taxonomy and Genetics: Belongs to the family Corytophanidae, genus Corytophanes. It is characterized by a laterally compressed body and a head topped by a prominent bony and skin-covered crest (casque) projecting backward. It possesses long, slender limbs suited for climbing and a very long, thin tail. Total length reaches 30-35 cm.
Behavior and Habits: Diurnal, arboreal, and highly sedentary. It employs a sit-and-wait ambush hunting strategy, remaining completely motionless on tree trunks for hours. Rather than running away when threatened, it freezes, inflates its gular pouch, and turns its head sideways to present a larger, intimidating profile to predators.
Morphology: The coloration is highly cryptic, consisting of mottled shades of dark brown, bark gray, and dull green, decorated with irregular markings that perfectly mimic moss, lichen, or dead leaves. Sexual dimorphism is subtle; males typically possess a slightly larger and more pronounced cranial crest than females.
Care, breeding and tankmates
Terrarium Setup: Requires a tall, vertically oriented forest terrarium (minimum 60x45x90 cm). The enclosure should be furnished with numerous vertical and diagonal climbing branches of varying diameters, cork bark slabs, and dense, broad-leaved live plants (e.g., Pothos, Monstera) to provide climbing paths and cover.
Lighting and Heating: Provide a localized basking spot temperature of 30-32°C, with a daytime ambient temperature of 25-28°C and a night drop to 20-22°C. A 5.0 UVB lighting source is essential to facilitate synthesis of vitamin D3 and prevent systemic metabolic bone diseases.
Humidity and Hydration: Maintained high humidity levels between 75% and 90%. Mist the enclosure thoroughly twice daily with clean, dechlorinated water or use an automatic misting system. These lizards rarely drink from standing bowls, preferring to lap water droplets from leaf surfaces.
Feeding and Supplementation: Strictly insectivorous. Feed on high-quality crickets, roaches, locusts, and occasional silkworms or earthworms. Dust prey items with pure calcium powder twice a week and with a multivitamin supplement containing vitamin D3 once a week. Ensure prey size matches the lizard's head width.
Compatibility: Solitary and territorial. Housing multiple individuals together in the same enclosure is highly discouraged. The visual presence of conspecifics causes chronic stress, leading to immune suppression, loss of appetite, and eventual decline.
Health and Common Diseases: Highly sensitive to excessive handling, which should be kept to a minimum. Common health issues include dehydration from lack of humidity, respiratory infections caused by stagnant water-saturated air, and Metabolic Bone Disease (MBD) resulting from inadequate calcium or UVB exposure.

The catalog's scalar value is 12.5 cm. The ReptTraits v1.2 source reports a maximum adult measurement of 12.5 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.
