Key facts

Adult size

approx. 180–240 cm, rarely up to 300 cm

Life expectancy

approx. 12–20 years in captivity

Origin

South and South-East Asia (from Iran and Afghanistan through India to southern China, Vietnam, Indonesia)

Protection status

Not in the CITES appendices; nationally protected or regulated in places – mind the origin (captive-bred rather than wild-caught)

Brumation

No real winter rest (tropical / subtropical); at most a slight seasonal drop in temperature for breeding

Cohabitation

Keep them singly. A very large, extremely active and defensive snake – put it with its own kind only briefly and under supervision for breeding; feed them separately because of the strong feeding drive (a risk of bite accidents and cannibalism).

Notes

Only for experienced keepers: hectically fast, nervous, a powerful biter, with a huge space requirement; often nervous wild-caught animals – prefer captive-bred ones and animals used to frozen/thawed food. Non-venomous. Detailed, reputable care sheets are scarce – the figures are a conservative consensus, hence medium confidence on the finer values.
