Red eyes

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)[reply]
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)[reply]

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)[reply]

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?

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.[reply]

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)[reply]

Tadpole Question

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)[reply]

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)[reply]

Distribution of species

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

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.

I study red-eyed treefrogs and the comment above is absolutely correct. The IUCN redlist (https://www.iucnredlist.org/species/55290/3028059) has it correctly as one word but unfortunately Amphibian Species of the World is currently listing it as "tree frog" -- maybe this issue is broader than just wikipedia.

Nictitating Membrane

— Preceding unsigned comment added by Abbieloring (talkcontribs) 04:08, 20 March 2021 (UTC)[reply]

Proposed Edits to this article

Behavior

"During the day, they remain motionless, cover their blue sides with their back legs, tuck their bright feet under their bellies, and shut their red eyes"

To this section, I think it would be useful to add information about the Nictitating membrane that covers their eyes while they sleep.

Red Eyed Tree Frog Nictitating Membrane New section proposal: During the day, they remain motionless, cover their blue sides with their back legs, tuck their bright feet under their bellies, and shut their red eyes. They do not have a true eyelid, but rather a Nictitating membrane that allows light to enter the eye so that they will awaken when predators are approaching. [1]

Reproduction

"The eggs develop into tadpoles, which hatch after six to seven days and fall into the water below."

My addition: Red eyed tree frog embryos use natural day and night light cycles as a signal for when to hatch, and tend to hatch just after nightfall. [2]

"Red-eyed treefrog eggs [may] hatch early (exhibiting phenotypic plasticity) when a change in the environment signals a danger to their survival"

I reviewed the article on Oct 20 and thought it was very good. I believed the diet section could be improved by adding more information about the role of carotenoids, so I made the following additions:

A study on carotenoids consumption has shown they play an important role in development, phenotype, and fecundity. [17] There is a critical window after metamorphosis where carotenoids improve female growth rate and fecundity, and lead to a redder skin in both sexes. Carotenoids are important nutrients for wild red-eyed tree frogs and especially for captive red-eyed tree frogs, who sometimes suffer skin pigmentation degradation due to an inadequate diet. — Preceding unsigned comment added by Luiscville (talkcontribs) 20:51, 8 December 2022 (UTC)[reply]

Edits

I'm working on this page for a class (Behavioral Ecology, Washington University in St. Louis) and I made several edits to the original page. I added an opening paragraph, as well as sections for Phylogeny, Genetic Distribution of Morphs, Life Cycle, and Mating Patterns. I also removed information that was not cited from the original post.

Updated information about conservation

As of 2016, the red eyed tree frog is classified as being of least concern because while the population is decreasing, it is classified as least concerned because of its tolerance to habitat modification, wide distribution, and presumably large population.[1] Qazwsx1515 (talk) 22:30, 17 October 2022 (UTC)[reply]
