Southern Banded Newt

The natural habitat of the species is water bodies of various types in temperate forests and grasslands, including rivers, ponds, and canals, and extending to water in caves, arable land and rural gardens. It has been found in water that has a temperature from 8.7 to 14.6 °C (average 11.4), a pH from 7.5 to 8, a GH (general hardness) from 3-18 (average 11.4), and a KH (carbonate hardness) from 3-18 (average 10.4). Generally they prefer higher altitudes (above 1500m) which have lower temperatures. When temperatures fall below 3.9 °C, they will go into hibernation and aestivating in dry, hot weather.

Their breeding season lasts from early spring to early summer (February to June). During this breeding season they inhabit shallow, slow flowing water with vegetation but otherwise inhabit wooded or areas of loose stones that are close to water. Also during this season, O. vittatus males develop large crests on their back and more vivid colors to attract the females along with using visual displays and movements with their tails and crests. The males are known to have aggressive and territorial behavior; they defend their territories by biting and chasing away other males and maintain a few tens of centimeters to 0.8 m of open space between their territories. Fertilization is internal but non-copulatory and the female will often accept multiple spermatophores (from different males).
