axylotl ?
Re the inland taipan. When I was working at Yass, the local gun club had a "king brown" snake in the target shed. Eventually they got hold of the snake (deceased), and one of them, an amateur herpetologist did a scale count (fore and aft of vent all that stuff), and reckoned it was a taipan. Never heard of down this far.
Took it to the CSIRO, and they confirmed it as a Tapian, but never seen down this far.
A few years later, the Fierce Snake was identified.
