Eastern Newt Life Cycle and Characteristics

The eastern newt is a fascinating salamander with three life stages: larval, red eft, and adult. Unlike other salamanders, it returns to an aquatic adult stage after being terrestrial. The larval stage is aquatic with external gills, while the red eft stage is terrestrial and poisonous. Adults are aquatic, breeding in water and laying eggs. They can adapt to environmental changes by returning to land if necessary. Some populations skip the red eft stage, remaining aquatic. Eastern newts face predation but have poisonous skin as a defense.
