北冠毛蝾螈种

大冠蝾螈一年中的大部分时间都在陆地上度过，主要生活在低的森林地区，在春季进入水中繁殖。雌性能产大约200个卵，孵化后，幼体需要两到四个月变态为陆生体。它以各种无脊椎动物为食。

The northern crested newt, great crested newt or warty newt (Triturus cristatus) is a newt species native to Great Britain, northern and central continental Europe and parts of Western Siberia. 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 blotches. During the breeding season, males develop a conspicuous jagged crest on their back and tail.

The northern crested newt spends most of the year on land, primarily in wooded areas of the lowlands. In spring, it moves to aquatic breeding sites, mainly larger fish-free ponds. Males court females with a ritualised display and deposit a spermatophore on the ground, which the female then picks up with her cloaca. After fertilisation, a female lays around 200 eggs, folding them into water plants. The larvae develop over two to four months before metamorphosing into terrestrial juveniles (efts). Both larvae and land-dwelling newts mainly feed on different invertebrates.

Several former subspecies of the northern crested newt are now recognised as separate species within the genus Triturus. Its closest relative is the Danube crested newt (T. dobrogicus). It sometimes forms hybrids with some of its relatives, including the marbled newt (T. marmoratus). Although it is currently the most widespread Triturus species, the northern crested newt was probably confined to small refugial areas in the Carpathians during the Last Glacial Maximum.

While the International Union for Conservation of Nature lists the northern crested newt as a species of Least Concern, its populations have been declining. The main threat is habitat destruction, for example, through urban sprawl. The species is also listed as a European Protected Species.
