Red eyes[edit]

Why are the eyes of this frog red? I believe it has something to do with the fact they are nocturnal, but I would like to know more specific details. - Joe H.

Most frogs are nocturnal, so it isn't that. I think it is just a pigmentation, like humans eyes are sometimes blue, and sometimes brown. It doesn't affect our eyesight. However, I will look it up. --liquidGhoul 00:44, 5 February 2006 (UTC)
From an evolutionary perspective, there doesn't necessarily have to be a reason the eyes are red. All eyes have to be some color, so I'm not sure that there's necessarily any adaptive value to it. Mechanistically, it would be interesting to see what pigments cause the red coloration.Pstevendactylus 17:10, 12 February 2006 (UTC)

There has been some speculation that the red coloration is a signal used to warn diurnal predators that have disturbed the sleeping frog. Although this frog is protected by some mild skin toxins, I'm not aware of any aditional evidence that supports this hypothesis. Grinter (talk) 19:00, 21 May 2010 (UTC)

I'm also not aware of any support for the warning coloration hypothesis. Furthermore, the skin toxins are pretty mild, and red-eyed treefrogs generally take a lot of harassment before they fully open their eyes (they can peek through their gold striped nictating membrane without exposing the color of their eyes). Work on the visual sensitivity of this species suggests they can see some color at night. I do not recall whether the red should be visable.

what are red eyed tree frogs useful for?[edit]

i am doing a report for my class, and in my report she would like to know if it is useful for anything. are they? --65.54.98.30 21:42, 17 October 2006 (UTC)erin v.

It depends on your definition of useful. Many people keep this species as a pet, and pets are useful for decreasing stress. They also hold an important ecological niche in their habitat. I don't know if it is best to ask me, as I think all species are useful. Humans shouldn't decide something like that, because then we start to decide their future, whether we should save them from extinction, based on our assumptions, and that isn't right. --liquidGhoul 23:24, 17 October 2006 (UTC)

Tadpole Question[edit]

Article says:

the tadpoles hatch and wriggle until they drop off the leaf into a pool of water below,

Who says there will be a pool of water under the leaf? Do the frogs make sure of this when laying the eggs? blah —Preceding unsigned comment added by 142.29.141.10 (talk) 21:17, 27 February 2008 (UTC)

Yes, the frogs make sure there is a water source below the leaf they lay onto. Otherwise the tadpoles would all die, and it would be a very bad adaptation to lay the eggs on leaves. --liquidGhoul (talk) 22:10, 27 February 2008 (UTC)

Distribution of species[edit]

This article claims that red-eyed tree frogs are "found in caves in the Appalachians." This seems absurd, and since there is no source posted and further research yields no confirmation, I ask that this "fact" either be confirmed or deleted by whoever added it. Thank you!

Treefrog[edit]

The common name of this species is the "red-eyed treefrog". For the wiki page, this keeps being changed back to "red-eyed tree frog". Because the frog is in the family Hylidae, it is a true "treefrog", and not just a "tree frog". ...and for that matter, the use of "tree frog" on the Hylidae page is even more of an embarrassment. If anyone could find a concise citation for this it would be helpful. There are hundreds of research studies using the correct names for hylids (and a handful for A. callidryas in particular), but these would be difficult to cite.
