The Smooth Newt is one of the most common amphibians found throughout temperate, forest areas in Europe. They are mostly terrestrial, only staying in water for extended periods of time during breeding season. They are also nocturnal, spending their days under logs and rocks. The newts do come out during rains during the day.
The Smooth Newt reproduces after the newt wake up from hibernation. The males and females move to ponds to breed. The males will grow out a wavy crest on their back to impress the females. The male will do a courtship dance to attract females. The males will deposit a sperm packet in the water and will lead a female over it during the courtship. The female will pick it up with her cloaca and bring it inside her to fertilize her eggs. A few days layer, the female will lay her eggs, as many as 300. Eggs hatch a few weeks later and larvae will appear. The larvae take a few months to complete their metamorphism, but some individuals may take over a year. These individuals will then have to survive in the water over winter.
In Australia, the Smooth Newt has established populations in the wild. It is believed the newts were released into the wild from a pet owner who didn’t want them anymore. Never do that please. Currently, it is not known if the newt is causing any serious environmental problems so the Australian Government isn’t actively trying to prevent their spread or eliminate them.
