General Species Information:
Found on Ellura (in the Murray Mallee, SA), the Adelaide Hills and elsewhere
5 fingers & 5 toes.
We've measured them from 35mm (juvi, S18) to 87mm (adult, S19) SVL (snout to vent length).
We weighed a large one, (85mm svl, S15, with full tail), which came in at 17g.
The juvi is the most colourful one we've come across.
The yellow spots on the backs & sides of these occur in highly variable patterns, and are raised protuberances. Some of them are very rounded and some are nearly spiny.
Underneath they have pink skin covered in white scales without any yellow protuberances.
The feet have thin toes that are clawed, no "suction" pads. As such they can't climb glass or slippery hard surfaces.
Notice S19 has lost it's tail in the past and regrown a new one. When this happen the new tail doesn't have any of the yellow spots, and is generally less colourful than the orginal tail.
