Key facts

Adult size

approx. 30–35 cm total length (mostly tail)

Life expectancy

uncertain; in captivity often only a few years (mainly wild-caught animals)

Origin

Central America, near the rainforest floor (southern Mexico to Colombia and Ecuador)

Protection status

Not listed under CITES; mostly wild-caught animals in the trade

Brumation

None; a slight seasonal change in photoperiod (about 13 h in summer / 11 h in winter)

Cohabitation

Single housing; territorial and highly stress-prone. 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

A sit-and-wait ambush hunter, slow and extremely prone to stress; often a food refuser (frequently taking only live prey). Usually imported as a wild-caught animal → high loss rates, unsuitable for beginners, and not an animal for handling. It needs high humidity AND air movement at the same time (otherwise shedding problems). The husbandry data are inconsistent across sources.
