The Mandarin Salamander (Tylototriton shanjing)
The Mandarin Salamander FAQ
by Marc S Staniszewski
INTRODUCTION
The small and primitive genus Tylototriton (family
Salamandridae) includes some of the strangest caudates known. There are five described
species which have been split into two sub-genera; Tylototriton and Echinotriton.
Echinotriton is so called because of the extremely sharp spines (from the Greek Echino
which means spiny or spiky) which, in 2 species, are able to penetrate through small
apertures in the flanks to act as a defensive mechanism against predation. The genus
Tylototriton contains the most colourful and primitive species of which one in particular,
the Mandarin salamander (Tylototriton shanjing (=verrucosus)) perhaps represents one of
the most stunning caudates. Fortunately it is this species which is most likely to appear
in the hobby, once due to large scale imports, recently as a result of small-scale
European captive breeding projects.
The beautiful markings make the Mandarin Salamander
(Tylototriton shanjing) a unique caudate species
DISTRIBUTION & BEHAVIOURAL
MECHANISMS
Also called the Emperor or crocodile newt, the
Mandarin salamander hails from the mountains of western China (primarily in the Himalayan
subregion of western Yunan), Burma, extreme northeast India, northern Thailand (where it
is probably extinct) and Nepal. Here it inhabits cool woodland and forest often in the
vicinity of slow-moving water. Attaining a length of 6 - 8 inches (15.24 - 20.32cm), its
vivid dorsal coloration of a dazzling orange vertebral stripe culminating in a completely
orange tail along with 12 - 14 orange rounded protuberances along the ribs on a black,
dark brown or maroon background makes it conspicuous. Therefore it would seemingly be
quite open to predation. However apart from being quite shy (which is anomalous with its
captive behaviour as can be seen later), its skin contains some rather distasteful and
potentially harmful alkaloids. In addition the skull and upper vertebrae are heavily
armoured with additional layers of thick bone (which gives it the appearance of wearing a
decorate crown hence the name emperor) which serves to deter predators. The startling
coloration actually enables it to bath freely in the open during the day where the
shifting reflection of light against the pebbly beds in the water enables a phenomenon
known as cryptic colouring (ie. the colours are broken up so that they merge with the
colours of the pebbles). Even so certain water snakes of the genus Natrix and raptors
(birds of prey) are known to prey on this salamander without displaying any adverse
effects. Therefore it is generally accepted that this is the main reason for the mandarin
salamander being primarily nocturnal in the wild - a trait which is not common in captive
specimens.
