Great Crested Newt
Triturus cristatus
The largest European newt, famous for the spectacular jagged crest developed by breeding males. It requires a cool seasonal cycle and a paludarium setup divided into aquatic and terrestrial zones.

Species description
Geographical Origin and Habitat: This species of newt is widely distributed across northern and central Europe, ranging from the British Isles eastward to the Ural Mountains. It inhabits a variety of semi-aquatic and wetland habitats, including deep ponds, vegetated drainage ditches, rural lakes, and damp deciduous woodlands adjacent to fresh water bodies.
Taxonomy and Genetics: Triturus cristatus belongs to the Salamandridae family. It is the nominate member of the Triturus cristatus species complex, historical for research in hybridization and speciation. It possesses a highly complex genome and suffers from a unique genetic anomaly known as 'chromosome 1 syndrome' which results in 50% embryonic mortality.
Behavior and Habits: Exhibits a dual life cycle: aquatic in spring (breeding season) and terrestrial in autumn-winter. During the aquatic phase, they are active day and night, swimming agilely and hunting crustaceans and insects. In the terrestrial phase, they are strictly nocturnal and fossorial, hiding under logs or stones.
Morphology: Reaches 14-16 cm in total length. Features rough, warty skin on the dorsum, colored dark brown or greyish with dark spots and tiny white dots on the flanks, while the belly is bright yellow or orange with asymmetrical black blotches. Sexual dimorphism is striking during the breeding season: males develop a jagged dorsal crest and a silvery tail stripe.
Care, breeding and tankmates
Terrarium Setup: Requires a spacious paludarium of at least 80x40x40 cm. During the aquatic phase, the setup must provide dechlorinated water 20-30 cm deep with dense aquatic plants (Elodea, Ceratophyllum) for egg-laying. During the terrestrial phase, a damp land area with peat, sphagnum moss, and cork bark refuges must be provided.
Lighting and Heating: They thrive in cool climates. Optimal temperatures during the aquatic phase are 14-18°C (57-64°F), while the terrestrial phase should not exceed 20-22°C (68-72°F). In winter, they require a hibernation period at 4-8°C (39-46°F) to stimulate breeding. A 2% or 5% UVB light is recommended for calcium absorption.
Humidity and Hydration: In the terrestrial phase, humidity must be maintained at 70-80% by misting the substrate regularly. In the aquatic phase, hydration is guaranteed by immersion, but it is critical to provide a floating island or ramp to allow them to exit the water.
Feeding and Supplementation: Strictly carnivorous. In water, feed mosquito larvae, bloodworms, daphnia, tubifex, and chopped earthworms. On land, offer appropriately sized crickets, small snails, and small earthworms. Dust terrestrial foods with calcium and vitamin D3 once a week.
Compatibility: Can be housed in small same-species groups (one male with multiple females). They must not be kept with predatory fish or other amphibian species to prevent disease transmission or predation of larvae. Males may show territoriality in the water.
Health and Common Diseases: Vulnerable to skin infections, both bacterial (Red Leg) and fungal, if water quality is poor or if the terrestrial substrate is waterlogged with stagnant air. Chytridiomycosis is a fatal risk. Handle only when absolutely necessary using wet hands or wet nitrile gloves.

The catalog's scalar value is 15 cm. The AmphiBIO v1 source reports a maximum adult measurement of 15 cm for this species, recorded as total length (TL). These figures are not interchangeable: the first is the profile's editorial reference, whereas the second is a published maximum under a specific measurement convention; differences among sources can reflect sex, population, life stage and measuring method.
