Reptiles and Amphibians

Currently in an argument- "too thin to be a Gila" vs "too beaded to be a chuckwalla"

Very sluggish, but it's only like 19c today. Maybe 25-30cm long

This is a Trachycephalus typhonius, formerly Trachycephalus venulosus, from Yucatan.

These frogs secrete a sticky and irritant milk-like fliud through its skin when bothered. Several years ago I got some some of that fluid into my eyes by accident - that hurts similar to scratching one's eye after touching a spicy pepper. So, they are not terribly toxic but I certainly do not recommend the experience.

Funnily enough I just ran a search and found a publication of someone who describes a similar but worse experience: https://www.thebhs.org/publications/the-herpetological-bulletin/issue-number-152-summer-2020-1/3101-09-a-caution-on-handling-i-trachycephalus-venulosus-i-anura-hylidae-toxic-effects-of-skin-secretion-on-human-eyes/file

You may notice that the finger pads of this frog look green. That's because its bones are green! A characteristic feature of this species. Here is a photo (not mine) of a skeleton of one of these : https://www.pybio.org/wp-content/uploads/2008/06/t-ven31.jpg

A new paper on a Bolitoglossid showed up in my alerts today! 🥳

It is a one-pager and comes with a beautiful photo of a foraging arboreal salamander 😄

Found this Imantodes cenchoa sleeping on top of a leaf in Punta Laguna, Quintana Roo.

Here is a photo of where it was sleeping:

There are a few different snakes of the genus Imantodes in Yucatán. What sets this species apart is that the row of scales on its back consists of enlarged scales. Here is a closeup emphasizing that row of scales. The green arrow points at an enlarged mid-dorsal scale, the blue arrow at a regular scale.

In comparison, here is a photo from an Imantodes tenuissimus that I took back in 2009 in Mérida, Yucatán (with a less sharp camera), and a closeup of its mid-dorsal scales that does not show this enlargement.

One of my favorite frogs! Spent some time specifically looking for it. Managed to find two near Cobá, in Quintana Roo (in the Yucatán peninsula). This frog hides in holes in lime stone and tree trunks, and makes use of its flat head to block the entrance. This type of defense is known as phragmosis.

Found this anole in Yucatan. I am not sure of its exact species - probably an Anolis sp..

Anoles often sleep at the tips of leaves and twigs. My guess is that this is a strategy to prevent nocturnal predators sneaking up on them through the branches without making its bed vibrate. When woken up they can quickly drop down.

Im noticing white chalky excretions in my tank but I'm not seeing any turds. Can the lizard still be blocked up or are they fine?

Found this little gal(?) In my bedroom all emaciated and sluggish, got her a heat pad, uv lamp and fattening it up with small crickets with calcium. Think it's a New Mexican Whiptail but not sure. Looks kinda wrinkly. Is it ok?

Hi -

Wondering if someone know a reputable rankin dragon breeder.

I’m first time reptile enthusiast and looking to find good trustworthy breeders in the US.

Thanks

Found many of these frogs under a wet trash bag in a back yard in Mérida, Yucatán. I made use of a handheld flash with a remote trigger for lighting, and a Sigma 105 mm as my macro lens.

These frogs do not seem to match with any of the local frogs reported in Julian C. Lee's field guide to the amphibians and reptiles of the maya world.

From a reverse image search, I mostly found images of the green house frog Eleutherodactylus planirostris. Eleutherodactylus planirostris is native to Cuba and the Bahamas, and is often introduced with plants that come from green houses in those areas. These frogs go from tadpole to frog while still inside of the egg, which explains why the baby frogs are so small.

The visual aspect, the incredibly small baby frogs, and the fact that they were found in a back yard in the city with greenhouse plants, all lead me to conclude that it is likely Eleutherodactylus planirostris.

Saw this nice guy/gal in front of my shed this morning when I took the dog out. The dog was completely oblivious and I was able to get a nice pic without scaring it off.!

sweet

About 2cm long! Cute as hell.

smh my head 😤

She's surprisingly good at climbing tho !

(actually just a Python Regius if you can't tell lol)

These guys are so pretty, they love hanging out around toilets in the outback.

Mt Magnet, Western Australia

Several 2cm long frogs were found in this tiny little granite pool in the desert. Any IDs would be welcome, I suspect it could be a Litoria of some sort.

Abstract

>Temperature is essential for the survival and development of eggs. Some anurans have evolved and developed foam nesting traits, with thermal insulation considered to be among their functions. Foam-nesting frogs tend to exhibit reproductive plasticity. For example, they oviposit on both trees and the ground. How such plasticity affects foam nest function is of major relevance and is likely related to the adaptation of foam nesting frogs. However, this has not been well studied. In this study, we examined the interaction between foam nest site, foam nest function, and egg fate using the Japanese green tree frog, Zhangixalus arboreus, and analysed how nest site differences (arboreal or terrestrial) affect the thermal function of foam nests. We compared the thermal functions of foam nests between arboreal and terrestrial oviposition sites of Z. arboreus. We artificially replaced half of the arboreal nests with terrestrial environments and recorded temperature in and outside of the experimental terrestrial nest and original arboreal nests. We also examined egg survival and hatching rates for all the nests. The results indicated superior heat insulation in terrestrial nests, with warmer temperatures inside than outside the nests, especially at night, which led to a high egg survival rate. Therefore, terrestrial ovipositing should be valid under cold weather conditions. This may be related to the evolutionary history of oviposition site plasticity of this genus, which originally had an arboreal oviposition trait but evolved into terrestrial site use owing to global cooling. Our novel insights into the evolution and adaptivity of foam nesting and oviposition site use in Z. arboreus make an important contribution to animal ecology.

I think that is what it is. Extraordinary climbers. I find them on the second floor of the house every few months. I see them outside a few times a week. Colouration is highly variable locally. Here they are green and black.

Wikipedia and a few other sources say this

> Also, it is reported to take snakes occasionally, and to avoid frogs, though frogs are also reported being eaten.

In Cambodia they always take frogs, and will strike poisonous toads, then spit them out.

Lovely things, quite relaxed as babies. This one was rescued from a palm tree after a storm. Another photo in body.

I was browsing through some literature about color-changing in chameleons and stumbled upon this relatively recent paper about how chameleons will change color where mosquitoes bite them.

!

From the discussion:

>While determining the particular mechanism(s) of color change is outside the scope of the current study, we nonetheless serendipitously discovered multiple instances of mosquito bite-induced color change in wild chameleons. This demonstrates that citizen science can produce discoveries of previously unknown natural phenomena, as our study represents the first formal documentations of mosquitoes feeding on chameleons as well as chameleon color change induced by arthropod hematophagy. These findings provide additional insights into the parasite-host interactions, such as the mosquitoes feeding on sleeping chameleons and particularly at the mouth.

Still a lot to do and fill out. All surfaces are sealed a long time ago and should be reptile safe. Cat palm is reptile safe from what I’ve seen.

The paper is from April, but I just became aware of it now!

Edit: We have already freed them. We were worried that they were poisonous and something could happen to our dog. Thank you very much to all.
