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. Go out to forage at dusk or after rain, and mostly prey on small harmful insects and small animals, mainly insects, earthworms, mollusks, loaches, etc. Hiding in the depths of caves during the hot afternoon of July; hibernation begins in October and comes out of hibernation in April. 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.
