Ambystoma mavortium

Even 40 cm long, Ambystoma mavortium stands among the biggest of western North America. Elegantly dotted livery and typical broad head with small eyes. Very common, usually spends the day in underground dens or vegetable debris and gets out hunting worms, molluscs and insects when gets dark, especially if it rains. In the reproductive time, by late winter-spring, the adults carry on aquatic life. The females lay small mucilaginous masses of 50-20 eggs that hatch in about one month. The larvae metamorphosize in summer © Giuseppe Mazza
