Two members of the glass-frog family Centrolenidae (Centrolenella fleischmanni, C. prosoblepon) and the hylid subfamily Phyllomedusinae (Agalychnis moreletii, 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. 

Infrared Reflectance in Chameleons (Chamaeleonidae) from Kenya

Five species of chameleons (Chamaeleo hohlzelii, schubotzi, graci/is, jacksoni, fischeri) were photographed in Kenya shortly after capture using Kodak infrared film, showing that several species of frogs reflect infrared light whereas others do not.

Convergence in reflectance spectra among treefrogs

It is suggested that thermoregulation by itself is not the primary biological role of high near infrared reflectance, and this capacity appears to be most likely associated with predator avoidance, functioning to make frogs visually and, perhaps, thermally cryptic to their predators.

ANTIPREDATORY BEHAVIORS OF THE COLOMBIAN ENDEMIC GLASSFROG CENTROLENE SAVAGEI (ANURA: CENTROLENIDAE)

The defense postures and production of odoriferous secretions is established as the first record of such behaviors for the family Centrolenidae, demonstrating that many aspects of the natural history of glass frogs are still unknown.

Avian Eggs: Thermoregulatory Value of Very High Near-Infrared Reflectance

Studies of the spectral reflectance of the eggs of 25 species of birds disclosed uniformly high reflectance in the near infrared, associated with the presence of the eggshell pigments protoporphyrin and the bilins, which allow coloration for cryptic or other purposes with minimum solar heating.

It is suggested that the unusual new pigment cell contributes significantly to the overall green color of C. fleischmanni.

Coloration of Anuran Tadpoles (Amphibia): Development, Dynamics, Function, and Hypotheses

The development, terminology, diversity, and functions of coloration in tadpoles are reviewed and a broad-based perspective that calls for an integration of several fields of research is strongly supported.

Glassfrogs of Ecuador: Diversity, Evolution, and Conservation

Diversification patterns are mostly congruent with allopatric speciation, facilitated by barriers to gene flow (e.g., valleys, mountains, linearity of the Andes), and that niche conservatism is a dominant feature in the family.

Both action potentials and evoked potentials were recorded from the tectum opticum of a crotaline snake, Trimeresurus flavoviridis, in response to infra-red stimulation of the facial pit organs, raising the possibility of stereoscopic perception.
