Origin

Iran, Pakistan, western, southern and north-western India (arid regions, semi-desert, rocky foothills)

Protection status

Protected: CITES Appendix II, EU Annex B - proof of origin required at purchase and resale. Nationally strictly protected in India (Wildlife Protection Act), export of wild-caught animals banned -> only acquire captive-bred animals; no registration requirement in Germany.

Not essential; for breeding a slight winter drop is possible

Cohabitation

Keep them singly – solitary and not sociable; putting them together creates needless stress

Notes

A burrowing desert boa; it spends almost all its time buried and needs plenty of floor area and deep digging substrate, but little height. No permanent damp (skin problems). Species-specific German-language data are sparse – some climate figures are derived from closely related Eryx species.
