a quick double-drabble (200 words) to try to help me get over my writers' block

.🐸.

Wei Wuxian didn't mean to turn himself into a frog. He did not start out his day planning to become two inches tall and sticky. But, as he pokes his head out from the seemingly gargantuan pile of crumpled silk that are his robes, he must admit, that is what he has done. 

He supposes he should probably be thankful that he's managed to keep his wits about him. This would all be much more difficult if he'd lost his mind as well as his body. His second body. Now third. He wonders if Lan Zhan would love him even like this. 

His husband’s soft golden eyes and quiet smile loop in his memory. “Wei Ying.” 

Yeah. He would probably build Wei Wuxian a home in their impossible mountain lotus pond. He would catch whichever bugs this particular species of frog likes to eat and toast them with chilies. 

That man. 

Luckily for both of them, Wei Wuxian does actually know how to undo this transformation. He hops easily onto the table, legs far more powerful than he anticipates, but wide-spreading toes that help him land gracefully. 

Now, if only he can figure out how to hold the calligraphy brush…

モリアオガエル

（学名：Zhangixalus arboreus)

両生綱無尾目アオガエル科アオガエル属

水面にせりだした木上に泡状の卵塊を産み付けることが特徴。

日本国内には泡状の卵塊を形成するカエルは二種類しかおらず、さらに地上に産むものはこの種のみ。

各都道府県レベルではレッドリスト(絶滅危惧種)入りしている場合がある。

A New Species of the Genus Zhangixalus (Amphibia: Rhacophoridae) from Vietnam

Hoa Thi NINH, Tao Thien NGUYEN, Nikolai ORLOV, Truong Quang NGUYEN, Thomas ZIEGLER

We describe a new species of the genus Zhangixalus Li, Jiang, Ren & Jiang, 2019 from Ha Giang Province, Vietnam based on morphological and molecular data. In the molecular phylogenetic analyses, the new species is nested in the Zhangixalus duboisi (Ohler, Marquis, Swan & Grosjean, 2000) group, where it is sister to Z. duboisi with a genetic distance of 2.51%.

The new species, Zhangixalus franki sp. nov., differs from its congeners by a combination of the following morphological characters: size large, SVL 77.9–85.8 mm in males; finger webbing formula I1-1II0-1III½-0IV; dorsal surface of head and body green with dark brown spots; ventral surface grey or dark grey, white stripe along edge of jaw, insertion of limbs, and along lateral ridges of fore and hind limbs and flank, separating upper green part from lower grey part.

The new species occurs in evergreen montane tropical forests at an elevation of ca 1300 m a.s.l. The new discovery brings the total number of known species in the genus Zhangixalus to 38 and the species number reported from Vietnam to nine.

Taiwan Treefrog (Zhangixalus moltrechti), family Rhacophoridae, endemic to Taiwan

Spot a treefrog in my garden. It called Zhangixalus arvalis, a species of frog in the family Rhacophoridae. Its upper tip is white, and the white color continues as a white stripe on the flanks.

I can add a little tid-bit about the frogs! Or at least the White’s Tree Frogs (all the frogs pictured minus the ones with red eyes and feet), I can’t comment much on the stacking (though I am definitely going to research it afterwards, my best guess is something temperature based as they are ectotherms (cold blooded) but I have no clue!)**. What I can say about is the colours! As you can see the frogs are all slightly different hues and that’s because frogs can change colours (or well certain sepiecies)! Frogs are very cool in the fact they have three (3) chromatophores* (colour pigments), for comparison humans only have one (1), which they can rearrange to form different colours! In order to do this the frogs form things called chromatophore units, which consist of all 3 pigments stacked (these can be found in the frogs skin), on top (so closest to the ‘outside’ of the frog) is xanthophores, underneath these are iridophores and then beneath these are melanophores (these also form ‘branches’ that come up the side of the irdiophores so they can block their reflective surface). To then change colours the frogs change the arrangement of the pigments as well as the orientation, spacing and thickness are changed (within layers) as well as having the melanophores move and cover the iridophores. This means frogs are able to change colour! Either slowly over time like what’s seen in White’s Tree Frogs (they do this to match their environment), but some species do it more rapidly like Zhangixalus smaragdinus can go from brown to green quite rapidly. Another even cooler thing is when there’s a complete absence of any pigments, then the skin goes semi-transparent as seen with the underside of glass frogs (Hyalinobatrachium ispidiense)! Though there isn’t a lot of research on them but it’s believed they have the semi-transparent to help with camouflage as it breaks up their silhouette!  *These 3 are: Xanthophores, iridophores and melanophores, with these respectively giving yellows & reds (xanthophores), being reflective so giving a white (iridophores) and giving dark shades with the use of melanosomes with melanophores **Looked into it and it seems like it’s a mating behaviour called amplexus, though I didn’t look too much so unsure if that applies for multiple frogs or not!
