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 being bitten, but the average is around 2.5 hours. The time between a bite and death depends on various factors such as the nature of the bite and the constitution of the victim. Untreated bites have a mortality rate of 100% as the coastal taipan always delivers a fatal dose of venom (an average bite delivers 10-12x the lethal dose of venom for a human adult male), and medical professionals recommend that victims seek immediate medical attention even for apparently minor bites. Before the introduction of specific antivenom by the Commonwealth Serum Laboratories in 1956, nearly all bites were fatal.
