Black Spiny-Tailed Iguana key facts

Care level

Advanced

Lifespan

15-25 years

Size

Males up to 1.3m, females 0.8-1m in total length

Temperature

Diet

Mainly plant matter such as leaves, flowers, stems and fruit, with insects and small animals taken opportunistically

Temperature & Humidity

Published figures give an enclosure air temperature of 24-29C with a basking area of 35-41C. Mist in the morning to reproduce the high morning humidity of its native habitat. As a sun-loving diurnal lizard it needs UVB lighting running over at least two-thirds of the enclosure length.

Enclosure

A single animal or a pair is commonly housed in an enclosure of roughly 240 x 60 x 60 cm, or 240 x 60 x 75 cm. As a rock-dwelling species it needs flat stones and driftwood arranged into crevices it can wedge into, along with basking surfaces and branches to climb. Provide a water bowl heavy enough not to tip over.

Diet & Feeding

Adults are largely herbivorous, taking flowers, leaves, stems and fruit and eating insects or small animals opportunistically. In captivity base the diet on leafy greens and flowers and keep animal matter as a supplement. Any plants placed in the enclosure should be non-toxic, since they will be eaten.

Temperament

It is extremely fast and, when cornered, lashes with its tail and bites. It is large and powerful, so handling requires patience and care. Males fight and must not be housed together.

Notes

Ctenosaura spp. have been listed on CITES Appendix II since 12 February 2020, so import requires an export permit from the exporting country; Appendix II animals need no Japanese registration certificate. It is neither a specified animal nor an invasive alien species under Japanese law. Given that it reaches 1.3 m and is powerful, secure housing and a plan for its whole life before acquiring one.
