Key facts

Life expectancy
20–25 years, individual animals longer
Origin
Eastern and southeastern Australia (coastal rivers and banks)
Protection status
— (no CITES; an Australian export ban, captive-bred animals only)
Brumation
A cooler overwintering period of several weeks up to 2 months. The western form (howittii) is more cold-adapted and needs the rest more clearly than the eastern form.
Cohabitation
A pair or group with one male; the males are territorial. The reason: several males fight over territory and the warm spot until one is injured or spends its life in a corner. Females usually get on, but each needs its own warm spot and hide; feed them separately once they differ in size.

Notes

Collective entry for both subspecies of Intellagama lesueurii. Care is nearly identical; the western form needs it a bit cooler and requires a more consistent winter rest.
