Its high number of dorsal scale rows (61–72 at midbody), makes the skin look smoother than that of other pythons.

[5] Unfortunately, this species is occasionally confused with the venomous king brown snake, Pseudechis australis, and may be mistakenly killed based on the misidentification.

[2] The diet of L. olivaceus consists of birds (ducks and spinifex pigeons), mammals (including rock wallabies and fruit bats), and other reptiles.

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.

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.
