Some, but not all, species of salamander hibernate during the winter months. Salamanders are classified as amphibians, and amphibians cannot regulate their own body temperatures.
Salamanders fall into two categories: terrestrial, or land dwelling, and aquatic, or water dwelling. If it lives on land, a salamander finds a burrow or other natural shelter in old logs or rocky places since salamanders cannot dig on their own. Terrestrial salamanders hibernate during winter months to avoid cold temperatures. During hibernation, the metabolic rate of the amphibian slows down drastically. Aquatic salamanders may stay active, even during winter months, under the ice of the aquatic environment in which they are living.
