In Hokkaido, there are many beautiful blue spots in nature, such as the "Blue Pond" in Biei and the "Blue Cave" in Otaru. One "natural blue" taken in a forest in Hokkaido has become a hot topic on SNS. The shocking beauty of the color has been attracting a lot of attention.

The blue of the Japanese cyprinid is beautiful, but this is the one that struck me the most as the blue of the natural world.
The egg sacs of Hokkaido's northern salamanders are really badass!
No wonder they are called the sapphires of the marshlands.

What they are is the vividly floating egg sacs of the northern salamander. The egg sac is a transparent agar-like pouch filled with many eggs, and the Northern Salamander's egg sac is called the "Sapphire of the Marsh" because of its shining blue-white color. The post received comments such as "mysterious," "I thought it was CG," and "It looks like it's breathing fire,

The Ezo salamander, endemic to Hokkaido, is also beautiful!

The contributor is CIDER, a photographer who mainly takes pictures of seasonal insects. The photo of a northern salamander egg sac was taken when he visited Hokkaido in April 2021. He also photographed the "Ezo salamander," a species endemic to Hokkaido, and its beautiful pattern on its back, which looks like it is covered in gold leaf, is mysterious.

Beautiful creatures living in Hokkaido. The northern salamander is found only in limited areas such as Kushiro Marsh, but the Ezo salamander is widely distributed in Hokkaido, so you may have a chance to find one.
