Great crested newt (Triturus cristatus) is a species of newt commonly found in Europe. It is characterized by its distinct appearance and notable biological features. This amphibian belongs to the genus Triturus and the family Salamandridae. The great crested newt is a protected species in many countries due to declining populations and conservation concerns.
The great crested newt is a medium-sized newt, typically growing between 10-17 centimeters in length, although females tend to be larger than males. It has a dark brown or black coloration on its back, with yellowish-orange undersides and a bright orange belly during the breeding season. Its most distinguishing feature is the jagged crest that runs along the male's back, which is larger and more pronounced during the breeding season.
These newts are primarily found in freshwater habitats such as ponds, lakes, and slow-flowing rivers. They are mainly nocturnal and semiaquatic, spending much of their time in water but also venturing onto land for foraging and breeding. Great crested newts feed on a variety of invertebrates including insects, worms, snails, and small crustaceans.
Breeding usually occurs between March and June, during which males display courtship behavior to attract females. Females lay their eggs on aquatic vegetation and the larvae hatch as fully aquatic tadpoles. After several months, these larvae undergo metamorphosis and become terrestrial juveniles.
Due to habitat loss and pollution, the great crested newt populations have decreased significantly. Consequently, they are protected under various conservation acts and their habitats are subject to legal protection. Conservation efforts focus on maintaining and creating suitable breeding sites, improving water quality, and raising awareness about the importance of protecting these unique amphib
