|Distribution of the olive python|
The olive python (Liasis olivaceus) is a species of snake in the family Pythonidae. The species is endemic to Australia. Two subspecies are recognized, including the nominate subspecies described here.Add reference
With adults reaching over 4 m (13 ft) in total length (including the tail), L. olivaceus is Australia's second-largest snake species (surpassed only by the amethystine python). Its high number of dorsal scale rows (61–72 at midbody), 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 cream-coloured.
Distribution and habitat
The olive python 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 burrows under rocks.
The diet of L. olivaceus consists of birds, mammals (including rock wallabies and fruit bats), birds (ducks and spinifex pigeons), and other reptiles. It prefers to lie in wait next to an animal trail to ambush its prey. Alternatively, it is a strong swimmer and also hunts in waterholes, striking at prey from under the water.
Mating activity of olive pythons starts in May and continues until mid-July. When successful, this is followed by a gestation period of 81–85 days, after which the oviparous female lays 12–40 eggs in late spring. The average clutch size is around 19 eggs. The hatchlings emerge after an incubation period around 50 days, each measuring about 35 cm in length.

The olive python is often kept as a pet and is bred in captivity. It is technically an advanced-level species due to its size, habitat requirements, and strong feeding response, requiring a terrarium of a minimum of 2.4 metres (8 ft) long, by 1 metre (3 ft) high and 1 metre (3 ft) wide. If raised properly, it is noted to be friendly, curious, and calm. In removing it from its enclosure, snake hooks be used so as to prevent the feeding response from being triggered, and once out, it can generally be freely handled calmly due to its placid nature.[better source needed]
