Description
A robust newt with granular skin and prominent boney
ridges on the head and spine. A row of warts runs down
each side. The dorsolateral surfaces of these
salamanders are marked vividly with orange, including the
cranial crests, parotoid glands, middorsal crest, and
lateral warts. In addition, the lower sides, limbs, tail,
and venter are various hues of orange-yellow (Nussbaum
et. al., 1995). The rest of the animal is dark brown to
black. The brightness of the orange markings varies
between yellow-orange to almost rust colored. Although
color varies between individuals, the patterns of the
markings are relatively constant. Only slight variation
is noted in the extent of orange coloration.
Natural Range and Habitat
Found in the Yunnan province of China. It lives in the
mountainous areas near the Nu, Yuan, and Lancang rivers.
(Mahoney and Vredenburg, 1999)
Housing
This species requires only a small body of water.
Although they rarely enter the water outside of breeding
season, its always best to have it there in case
the cage becomes too dry. Completely terrestrial, it
should be given plenty of land area as well as places in
which it can conceal itself. I have found that tightly
packed soil approximately 2 to 3 inches deep works
wonderfully. Use the substrate to create a moisture
gradient so that one end of the enclosure is very wet and
the other dry. Do this by adding water to only one end of
the enclosure, it will slowly seep through the soil. This
allows the animal to choose what it prefers. Do not allow
the soil substrate to become muddy or too much moisture
to build up, as they prefer fairly arid conditions.
Feeding
If healthy, they feed well on a variety of foods. Common
sources are wax worms, earthworms, chopped night
crawlers, mealworms, and crickets. Feed a variety to
assure balanced nutrition.
Breeding
In the wild they typically breed May through August. They
deposit eggs on rocks and plants in standing water bodies.
(Mahoney and Vredenburg, 1999) In captivity, breeding can
be initiated by mimicking their natural seasonal
conditions. One way is to keep the animal in the lower 60s
and on a fairly dry substrate during the winter. Then
during summer, raise their temperature to the upper 70s
and increase the humidity. If breeding is to occur,
supply the captives with enough water for courtship and
for depositing eggs, while still maintaining a nice sized
land area.
