Origin

Uncertain – probably the Papua / New Guinea region (a tree monitor of the prasinus complex)

Protection status

Varanus generally falls under CITES Appendix II / EU Regulation Annex B (proof of origin needed); the exact status is uncertain because the taxonomy is unresolved

Brumation

None

Cohabitation

Single housing – tree monitors are territorial/solitary; never males together. The reason is territory: two animals will not voluntarily share a basking spot or a hiding place. They fight until one is seriously injured or permanently confined to a corner — and that second animal then eats worse, without showing any visible wound.

Notes

NOTE: "Varanus boatsi" is NOT a name listed or valid in the Reptile Database (not found). Most likely it is a corruption of "Varanus boehmei" (Böhme's / golden-spotted tree monitor, Waigeo) or another tree monitor of the prasinus complex. The figures here are set as guide values for the prasinus/boehmei complex and are UNCERTAIN. Correct and verify the scientific name before integrating it into the app.
