It is a large newt, with females growing up to 16 cm (6.3 in) long. Its back and sides are dark brown, while the belly is yellow to orange with dark ...
In the absence of suitable plants, the eggs may also be deposited on leaf litter, stones, or even plastic bags. In the northern crested newt, a female takes around five minutes for the deposition of one egg. Crested newt females usually lay around 200 eggs per season, while the marbled newt (T. marmoratus) can lay up to 400.
Newts are semiaquatic, spending part of the year in the water for reproduction and the rest of the year on land. While most species prefer stagnant water bodies such as ponds, ditches, or flooded meadows for reproduction, some species such as the Danube crested newt can also occur in slow-flowing rivers.

Female mate choice is an important concept in evolutionary biology because it bears on female and male reproductive success. Experiments were carried out with Lissotriton vulgaris in which female newts were paired sequentially with two males having different degrees of genetic relatedness to the female.

The tadpoles also exude noxious substances which deter fish from eating them but not the great crested newt. Aquatic invertebrates that feed on toad tadpoles include dragonfly larvae, diving beetles and water boatmen. These usually avoid the noxious secretion by puncturing the tadpole's skin and sucking out its juices. [22]
