Key facts

Adult size

Life expectancy

12–20 years

Origin

Madagascar (western and northern Madagascar, drier regions)

Protection status

Rear-fanged (mildly venomous, usually harmless to people, but still take care) – not listed under CITES; a Madagascan endemic, so prefer captive-bred animals.

Brumation

None as such; a slightly cooler, drier rest period to stimulate breeding is possible

Cohabitation

Keep them singly – it can be cannibalistic or snake-eating, and it is solitary; put them together only briefly for supervised breeding

Notes

An active, burrowing daytime hunter – deep digging substrate and a secure cover (an escape artist). Rear-positioned grooved fangs: stronger local reactions are rarely possible from a bite. The size figures for L. modestus are partly mixed in the sources with the larger L. madagascariensis – set conservatively here.
