Hyla japonica
Japanese tree frog

Photograph by Baikada (ばいかだ)

Because I wanted to explain a lot when this photograph is improved, it has written a lot. However, only the last several lines of sentences are messages that I want to write.

Japanese tree frog is usually green. It changes blackish in case of being on the soil. Moreover, it changes into the gray. However, I think the individual that yellows like this not to be seen so much either. In a word, I think that it is a color mutation.

I was anxious about yellow color of it, and put it on the leaf for two hours. It came to look very little a color like green when often seeing though body color of it was yellow. The coloring matter seems to have abnormality though it is not complete yellow. Because my favorite is a color mutation and an individual variation, I want to take a lot of photographs.

When I began to look for the snake, the one that Japanese Forest ratsnake is red was called “Red Burrowing ratsnake”, and guessed to be another kind. However, I confirmed Burrowing ratsnake and Red Burrowing ratsnake appeared from the egg that parents of same Burrowing ratsnake had laid at the same time. It was a color mutation. I began to live in the Okhotsk area in Hokkaido, and observed the snake. I thought that many did not have the light color in Japanese rat snake, and there were a lot of ones light blue and light green. I saw a lot of Japanese four lined snake that were not have line. I saw a jet-black Japanese four lined snake.

A lot of color mutations of Tiger keel back were seen in the Kansai area west this year. Externals change by the mistake of the variety and looking when the color is different. I wanted to up the pattern as a lot as possible as a body that bit the site of snake’s picture book. (It is thought that the page of Japanese mamushi holds out considerably. ) To post of each on an English site, I had to study the technical term.
They are words considerably used in a pet industry.

The individual with strong red is “Erythristic”.
The individual without the red dye oppositely is “Anerythristic”.
The individual with strong pigmentum nigrum is “Melanistic”.
The opposite is “Amelanistic”.
In addition, the individual with a little pigmentum nigrum is “Hypomelanistic”.
The individual of which the yellow pigment goes out strongly is “Xanthic”.
The opposite is “Axanthic”.
All lacked individuals are “Albino” as for the coloring matter.
(Eyes are red of blood. )

There is a thing that the word “Amelanistic” is used in the same meaning as “Albino”. When any one color is lacked, “Albino” is like the word used. I am very confused. The difference whether the word “Albino” is used in a broad sense or use it in a narrow sense.

I took time to learn it. However, these words are essential to write in particular color variation of Tiger keel back in English.

By the way, Japanese tree frog  in the photograph might only have to be called what color mutation?

It might be reported that light blue Japanese tree frog was discovered sometimes. This is explained, “Because yellow had been lacked among body color of green Japanese tree frog, became blue”. In a word, it applies to “Axanthic” (The yellow pigment is lacked).

When it is this theory, this Japanese tree frog will do blue coloring matter equivalent a decrease. However, the word that applies to “A blue coloring matter is a little” even if it examines it is not understood. The word “Acyanothic” might apply to this Japanese tree frog that a blue coloring matter is a little if going from the affiliate of the living thing coloring matter. Blue coloring matter (Cyanophore) seems to be found from the fish named psychedelically fish (Synchiropus picturatus) .

However, blue of Japanese tree frog is different. Blue of a blue coloring matter is like subfusc blue.

And, the word that I found is “Iridophore”. When light is hit, Iridophore seems to be seen blue about the shine a little in case of Japanese tree frog walking though is not an appearing coloring matter the color. (There seems to be not only blue but also a yellow, white one in fish’s Iridophore. ) Because this yellow Japanese tree frog is “Iridophore is a loss”, it is “Aniridothic”. No… Because a green taste was worn very slightly,,, because it is “Iridophore decreases”,,, it is “Hypoiridothic”?

Though I thought hard… It seems to call a green frog when actually examining it and to be called all individuals that have yellowed “Xanthic” (The yellow pigment is strong).

The following sentences are only Japanese. I’m sorry.




私達が「新型鳥インフルエンザ」を警戒するように、 ツボカビにも変異が起こって突然、日本で猛威を振るうことも考えられなくは無いです。(インフルエンザほど、変異の起こりやすいものではありませんが)リスクを考えて、行動するということは大切なことだと思います。


消毒すること、啓蒙すること、他にもなにかやれるときがあるかもしれない。「のらがへる 負けるな、ばいかだ これにあり」 なんて言えたらかっこいいね。
