Neurergus crocatus, the yellow-spotted newt, Azerbaijan newt, Azerbaijan mountain newt, mountain newt, or Lake Urmia newt, is a species of salamander in the family Salamandridae. It occurs in the mountains west of Lake Urmia, in northwestern Iran, northeastern Iraq, and southeastern Turkey.
Description
Neurergus crocatus grow to about 16–18 cm (6.3–7.1 in) in total length; the tail is longer than the body (i.e., tail length>snout–vent length). The head is flattened and longer than it is wide. The snout is rounded. The body is slender and almost round, without a dorsal ridge. The tail is rounded at the base and laterally compressed towards its tip. The tail has moderately developed dorsal and ventral fins. The limbs are well-developed; the digits are thick and flat. Colouration is dorsally dark brown to black with yellow, rounded but somewhat irregular blotches; these continue on the tail. The ventral surfaces are orange-red in males and yellowish in females. They can live for between 12-15 years in captivity, and usually reach sexual maturity in four years.
Habitat and conservation
Neurergus crocatus breed in montane streams at elevations of 1,500–2,000 m (4,900–6,600 ft) above sea level; after the breeding season, adults disperse to the surrounding areas, but their specific microhabitats are unknown. This species is probably threatened by habitat loss, caused by for example new dams.
Notes
- Despite its vernacular names, this species does not occur in the Republic of Azerbaijan. Instead, "Azerbaijan" here refers to the Azerbaijan region of Iran.
