It lives on the islands Ladigue, Felicite and Cocco in the Seychelles, and typically inhabits trees and dwellings.

On the back there are irregularly shaped reddish dots and bars present which can be quite variable in appearance.

Unpaired P. sundbergi ladiguensis are prone to fighting, sometimes causing significant injury or death if not quickly removed.

In captivity, these animals can be fed with crickets, wax moth larvae, fruit flies, mealworms and houseflies.

A commercial powered Crested Gecko diet (made by Repashy and mixed with water), supplemented with occasional insects, works well and supports breeding.
