Inland taipan hatch two months later. The eggs are usually laid in abandoned animal burrows and deep crevices. Reproduction rate depends in part on their diet: if there is not enough food, then the snake will reproduce less. Captive snakes generally live for 10 to 15 years. An inland taipan at Australia Zoo lived to be over 20 years old. The mulga snake ("Pseudechis australis") is immune to most Australian snake venom, and is known to also eat young inland taipans. The perentie ("Varanus giganteus") is a large monitor lizard that also shares the same habitat. As it grows large enough, it
Coastal taipan is exceeded in length among venomous snakes only by the Asiatic king cobra, African black mamba, and genus "Lachesis" (bushmasters) of the American neotropics. The head of the coastal taipan is long and narrow like that of the African black mamba ("Dendroaspis polylepis"), but without the "coffin" shape. The two species are strongly convergent in several aspects of morphology, ecology and behaviour. "O. scutellatus" has an angular brow and is lighter-coloured on the face. The body is slender and colouration can vary. It is often uniformly light olive or reddish-brown in colour, but some specimens may be dark gray to
