eggs. Their digit tips are expanded, allowing them to climb, thus allowing most to live in elevated areas along forest streams, such as trees and shrubs. Glass frogs are similar in appearance to some green frogs of the genus Eleutherodactylus and to some tree frogs of the family Hylidae. However, hylid tree frogs have eyes that face to the side, whilst those of glass frogs face forward. Two members of the glass-frog family Centrolenidae: Centrolenella fleischmanni, now called Hyalinobatrachium fleischmanni, and C. prosoblepon, and of the hylid subfamily Phyllomedusinae: Agalychnis moreletii and Pachymedusa dacnicolor, reflect near-infrared light (700 to 900 nanometers) when examined by infrared color photography. Infrared reflectance may confer adaptive advantage to these arboreal frogs both in thermoregulation and infrared cryptic coloration. Lifecycle Mating Mating begins by the call of a male tree frog, who is perched either on the underside or top of a leaf over a lake edge or a stream. Once a female has responded to the male's call, mating begins on the leaf in the amplexus physical position, in which the male wraps his arms around the female and attaches himself to her back. Once the physical mating process has concluded, the female produces her eggs onto the leaf before departing, leaving the male to defend the newly-laid eggs against predators. Males will occasionally call for and mate with other females on the same leaf, establishing a multitude of different developmentally-staged egg clutches to guard. Tadpoles Once the tadpoles, the frog aquatic larval stage, have been hatched, they fall from their original position on the leaf into the water below. When living in the water the tadpoles feed on the leaf litter and streamside detritus until undergoing metamorphosis to become a froglet. Conservation Predators A main predator on the glass frog in its tadpole stage are "frog flies", which lay their eggs within the frog eggs; after hatching the maggots feed on the embryos of the glass frogs. Protection All glass frogs are protected under the Convention on International Trade in Endangered Species (CITES) meaning that international trade (including in parts and derivatives) is regulated by the CITES permitting system. Distribution The Centrolenidae are a diverse family, distributed from southern Mexico to Panama, and through the Andes from Venezuela and the island of Tobago to Bolivia, with some species in the Amazon and Orinoco River basins, the Guiana Shield region, southeastern Brazil, and northern
