Quick Summary

The alpine salamander (Salamandra atra) is an ovoviviparous tailed amphibian found in the Alps. This means it retains its young within the uterus until metamorphosis is complete, giving birth to live, fully developed offspring. Unlike many other salamanders that lay eggs and have an aquatic larval stage, the alpine salamander bypasses this phase entirely.123

Alpine salamanders are part of the family Salamandridae, which are known for their toxicity, possessing poisonous skin or glands that secrete poison when threatened. These amphibians are generally nocturnal and can be found in various habitats, including alpine areas.34
