Err, yes very pretty indeed but owning one of them would be like one of them ppl-eating anaconda. The olives are big enough for me. I don't want to be a meal.
They are my favourite python species, an extremely beautiful snake with wonderful orange eyes (usually) and a somewhat unpredictable temperament.
Here's is a friend of mine with a captive one in the UK.
Check out the latest Reptiles Australia mag, it's a "Big Snakes" special & has some good info on retics (& others, including our own scrubbies & olives)
