Notophthalmus is a genus of salamanders commonly known as newts, primarily found in North America. They are characterized by their smooth skin, vibrant colors, and aquatic larval stage. Adult newts typically inhabit freshwater environments like ponds and streams, where they can be observed swimming or basking. These amphibians undergo a complex life cycle, starting as eggs that hatch into larvae. After a period of growth, they metamorphose into adults, which can live both in water and on land. Notophthalmus species play a vital role in their ecosystems, serving as both predators and prey.
