Salamandrella keyserlingii Detailed Introduction

The Arctic salamander, also known as the water snake, can be called a "living fossil". It is an ancient rare animal with an evolutionary history of 230 million years. In April 2022, photography enthusiasts from Dongfanghong Forestry Bureau Co., Ltd. found two relatively rare Arctic salamanders in a small stream by the roadside while collecting folk songs at Donglin Management Office.


The habitat is humid, mostly under the grass or in caves in swamps.

It breeds from early April to May, lays a pair of egg bags, and sticks to dead branches in the water. After laying eggs, it returns to land to live.


Its natural enemies are mainly tadpoles of other frogs, whose development period overlaps with that of the Arctic salamander, but frog tadpoles develop quickly, are large in size, and have strong swallowing power, and often feed on the juvenile Arctic salamander.
