Certainly a fun fact 😄 Reminds me of the painful sandspurs that stick one’s feet while walking through the beach.

Good question. The green pigment is biliverdin, which is a product of the breakdown of heme. But more specifically I am not quite sure, I’ll have a look.
I have found this open access article from 2020:Taboada, Carlos, et al. “Multiple origins of green coloration in frogs mediated by a novel biliverdin-binding serpin.” Proceedings of the National Academy of Sciences 117.31 (2020): 18574-18581.
This article goes into more specificity about the protein that binds the pigment and allows it to become concentrated inside of the body and bones. In this article they suggest that green is a difficult color to make, and that multiple frogs have evolved in parallel this mechanism to sequester the green biliverdin within the body, develop a translucent skin, and become green this way (for camouflage).
However, the common milk frog is not very green. It could be that the biliverdin-binding protein is a trait that is derived from an ancestor and is now vestigial. In the cited article, near the end, they do include a section “Other BBSs Functions”. In this section they point out that some frogs with green bones do not look green, and suggest that the protein could be involved in inflammation pathways and behave as an anti-oxidant. But nothing conclusive.
I quickly skimmed for other recent papers but I can’t find anything conclusive.

Careful. Big Taxonomy doesn’t mess around.
- Comment on Verticillium sp. (I think) 1 day ago:
Hey, thanks a lot! I agree with your assessment.
I spent some time looking through pictures and these Verticillium photos were the best matches I could find:
researchgate.net/…/Conidiophore-bearing-conidia-h…
…slidesharecdn.com/…/Tomato-verticillium-wilt-8-3…
But that Acremonium certainly looks like an even better match. And you are completely right in pointing out that the arrangement seen in my image is irregular whereas the Verticillium images show a more regular symmetric relationship between the condiogenous cells (term of the day for me).

Beautiful!
What does “rebloom” mean? Did it bloom twice in one year?

A danger noodle to sleeping lizards! But to humans these are inoffensive :)

Wow! That took me a moment to spot 😁
- Comment on Yucatan casquehead tree frog 4 weeks ago:
I agree! From the frogs in Yucatán, the one in this picture and the Mexican burrowing toad (Rhinophrynus dorsalis) are the coolest looking (in my opinion). I have looked and looked for the burrowing toad but I have never found one.

Hmm… Some lichen make use of orobatid mite labour in order to disperse the cells of their photobionts. Are those still ok?

That’s so cool! 😄 You are lucky to have anoles in your potted plants, enjoy them! I have returned to the Netherlands and reptiles are not too common around here 😔

Good news! Just got a reply from them and they have increased the connection limit. They did not specify what the new number is, but hopefully it is high enough to not be an issue for the foreseeable future.
So, if you do run into other similar reports after this comment I would appreciate it if you tag me again.
- Comment on Tell me Y 2 months ago:
Thanks!
Cost is not the bottleneck in this case… The problem is that I am rather ignorant about the options and their benefits/limitations. Moving the images the first time was painfully slow because of those same rate limits, and I expect the next migration to be the same, so I want to make a better choice next time and would rather find a solution with the current provider 😅
- Comment on Tell me Y 2 months ago:
Thanks for the heads up. I am still trying to resolve this without a migration… I will try again to get a response from them as they have not replied in a week.

And you are doing a great job at that! 😄
Very interesting article, thanks for sharing. I agree that it is a good one to pin!!
