Liasis olivaceus, commonly called the olive python, is a python species found in Australia. With adults reaching over 4 m in length, this is Australia’s second-largest snake species. Its high mid bodydorsal scale count, 61-72, makes the skin look smoother than that of other pythons. The number of ventral scales is 355-377. The colour/pattern is a uniform chocolate brown to olive green, while the belly is usually a cream colour. Unfortunately, this species is occasionally confused with the venomous king brown snake, Pseudechis australis, and killed as a consequence.
This snake is found in Northern localities throughout Australia in Western Australia, Northern Territory and Queensland. The type locality given is “North Australia; Port Essington” (Northern Territory, Australia). It occurs in rocky areas, gorges and especially rocky areas near sources of water. Typically, shelter is sought in caves and rock crevices, but individuals have also been found in hollow logs and in burrows under rocks.
Mating activity starts in May and continue through until mid-July. When successful, this is followed by a gestation period of 81–85 days, after which theoviparous females lay 12-40 eggs in late spring. The average clutch size is around 19 eggs. The hatchlings emerge after an incubation period of about 70 days, each measuring about 35 cm in length
