Tiger Salamander
Ambystoma tigrinum
🌍 Overview
The tiger salamander is the largest land-dwelling salamander in North America, found across a vast range from Canada to Mexico. They are burrowing animals that spend most of their lives underground, emerging to breed in temporary and permanent ponds. In some lake environments, individuals remain permanently aquatic and sexually mature without fully metamorphosing — a neotenic phenomenon. Some of these neotenic populations were historically described as entirely separate species before genetic analysis revealed their true relationship.
