In Jurassic World one of the scientists said that tree frogs can modulate their infrared output. Is this science fiction or science fact?

    While this is an interesting question, I wonder if it might be more appropriate on Biology.SE Commented Jul 23, 2015 at 4:51

    You're right. It is an interesting question! Commented Jul 23, 2015 at 5:54

    Other people are going to be searching for this information online. Do we want them to go to biology.se or join the conversation here? Is it against the rules to overlap? Edit - it's not. It's sci-fi but may also be sci-fa. Commented Jul 23, 2015 at 6:04

    We don't not close/migrate questions just because we want to attract new users. Ask about tree frogs within the JP/JW universe, and it's on-topic here; ask about real-life biology of tree frogs, and it's not.

    In response to the "on hold" reason stated above, the question seeking a scientific solution IS related directly to a cited work of fiction, namely, the film entitled Jurassic World, and is a contributing factor to an important part of the plot in said film. I imagine I'll be shouted down for this since I'm fairly new and all, but I see no reason why this question can't be taken off hold and be allowed to be answered. Commented Jul 23, 2015 at 17:31

Extract from wikipedia article on Multi-spectral camouflage:

"The English zoologist Hugh Cott, in his 1940 book Adaptive Coloration in Animals, wrote that some caterpillars such as the eyed hawk-moth Smerinthus ocellatus, and tree frogs such as the red-snouted treefrog Hyla coerulea, are coloured so as to blend with their backgrounds whether observed in visible light or in infra-red." (emphasys mine)

On the article there are documentation links referencing the appropiate bibliography.


According to this 1977 paper, some Glass frogs are infrared camouflaged. They can't manipulate this, but is just a natural trait of their skin. Some frogs can camouflage themselves like chameleons though.


"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."
