Descrição da espécie
Geographical Origin and Habitat: Native to the Himalayan region and Southeast Asia (including northern India, Nepal, Bhutan, Myanmar, western China, and northern Thailand). They inhabit damp montane forests, valleys, and river banks.
Taxonomy and Genetics: Belonging to the family Salamandridae. Commonly known as the Crocodile Newt or Shanjing. They are terrestrial for most of the year, returning to ponds only to breed.
Behavior and Habits: Strictly terrestrial and slow-moving outside the breeding season. If threatened, they secrete irritating toxins from their orange lateral warts and perform defensive displays (Unken reflex), curving their body to show orange tones.
Morphology: Reaches 15–20 cm in length. Females are significantly larger, wider, and heavier than males. Breeding males are distinguished by a swollen cloaca and a slightly taller tail fin.
Cuidado, criação e companheiros de tanque
Terrarium Setup: A damp horizontal terrarium or paludarium (minimum 80x40x40 cm) is required. Provide a deep, soft substrate layer of organic soil, leaf litter, and live sphagnum moss. Furnish with cork bark hides and smooth rocks. Provide a shallow, wide water dish.
Lighting and Heating: Montane species. Keep temperatures cool between 16 and 23°C. Temperatures constantly exceeding 25°C are hazardous. Avoid heat lamps or heaters. Provide low, ambient lighting and low-output (2–5%) UVB.
Humidity and Hydration: Maintain high humidity levels of 70–90%. Mist regularly with clean dechlorinated water to keep the moss damp, but avoid waterlogged soil which causes root and skin issues.
Feeding and Supplementation: Slow-moving carnivores. Feed on chopped or whole earthworms, small slugs, crickets, and soft beetle larvae. Feed adults 2–3 times a week. Dust food with calcium and multivitamin supplements twice a week.
Compatibility: Peaceful. Can be housed in small groups of similarly sized adults if multiple hides are provided. Do not mix with other species.
Health and Common Diseases: Heat stress is highly lethal. Dirty substrates lead to fatal fungal and bacterial skin infections. Avoid handling with bare hands; wear wet, powder-free nitrile gloves.

Perfil anfíbio
- Dieta
- Carnivore
- Voracious carnivores that feed on a variety of invertebrates, small fish, and amphibian larvae in the wild. In captivity, their diet should consist of earthworms, crickets, roaches, and aquatic foods like bloodworms and pelleted diets when in their aquatic phase. Supplementation with calcium and multivitamins is necessary for terrestrial prey items.

- 10-25 years
- Tamanho adulto

- Estilo de vida/Microhabitat
- Semi-aquatic
- Highly adaptable amphibians that transition between terrestrial and aquatic phases depending on the season and environmental conditions. A spacious paludarium with a large terrestrial area of moist soil and leaf litter, alongside a substantial water section, is ideal. They prefer cooler temperatures ranging from 15-22°C (59-72°F) and are intolerant of extreme heat.
- Ciclo de atividades
- Crepuscular
- Primarily nocturnal and crepuscular, though they often learn to recognize feeding times and may become active during the day in captivity. They tend to hide under leaf litter or logs during the brightest parts of the day. Their activity level increases significantly during periods of high humidity or rain simulation.
- Socialidade
- Solitary
- They are relatively bold newts that can become quite active and visible during feeding times. They possess granular, warty skin and prominent cranial ridges that give them a crocodile-like appearance. While generally peaceful with their own kind, they have a strong feeding response and may accidentally snap at cage mates during feeding frenzies.
- Reprodução
- Oviparous
- Breeding is closely tied to the monsoon season in their native habitat, requiring a significant increase in water level, temperature, and humidity to trigger courtship. Males develop a swollen cloaca and display by tail-fanning to waft pheromones toward females. Females lay small clutches of eggs attached to aquatic vegetation or submerged objects, which hatch in about two to three weeks.
- Toxicidade
- Toxic
- The prominent orange warts along the sides of the Himalayan crocodile newt are actually poison glands. When severely threatened or roughly handled, these glands exude a sticky, noxious secretion to deter predators. While the toxin is not generally lethal to humans, it can cause severe irritation to the eyes and mucous membranes. It is crucial to wash your hands thoroughly after any contact with this species to avoid uncomfortable side effects.
- Estágio de vida
- Metamorphosis
- The species undergoes a typical amphibian life cycle featuring an egg, an aquatic larva, and a terrestrial adult phase. The aquatic larvae possess large, feathery external gills and a finned tail to navigate their temporary pools. After a few months, they complete metamorphosis, losing their gills and developing lungs to survive on land. The juveniles then leave the water, sporting a darker, rougher skin texture than their aquatic larval counterparts.
- Tolerância de tratamento
- Display only
- They are a display-only species. Handling causes them significant stress, during which they may secrete toxic milky fluids from the bright orange warts running down their backs. Human body heat is also distressingly high for these cool-weather amphibians.
- Brumação
- A distinct seasonal temperature cycling is critical. They require cool summer temperatures (maximum 22°C / 72°F) and a distinct winter cooldown drop to around 10-14°C (50-57°F) to maintain their metabolic health and induce the aquatic breeding phase.
- Muda
- Periodic
- Shedding occurs regularly but goes largely unnoticed as they typically consume the shed skin immediately. Terrestrial shedding requires a very high ambient humidity, which can be provided by ensuring the moss in their land section remains continually damp.
