Italian Crested Newt

About the Italian Crested Newt

The Italian crested newt (Triturus carnifex) is a species of newt in the family Salamandridae. Triturus carnifex is found in parts of the Balkans and Italy. It is an aquatic breeder that can spend up to four months in the water. The location of the ponds where they breed affects the time when T. carnifex enters the water. T. carnifex prefers living in deep water since it is a nektonic species: it swims freely and is independent of currents. The absence of predatory fish may also explain why T. carnifex is inclined to ponds, rather than other larger bodies of water.

They typically prefer ponds in northern Europe, where temperatures are colder. Adult T. carnifex start to arrive between February and May, and leave between July and October. In warmer ponds, adult newts arrive within a month and leave during a two-week period in July. Andreone and Giacoma (1989) speculated that newt migration into the ponds increases after rainy days, since after rainfall, newt activity is not limited by humidity.

Higher altitudes, where temperatures begin to decrease, have a direct effect on the size of T. carnifex. Ficetola et al. (2010) discovered that living in colder temperatures resulted... Wikipedia →
