Phymaturus cf. palluma in Captivity: Observations on its Reproduction and Biology

Abstract. The herbivorous high-altitude iguanid lizard Phymaturus cf. palluma is adapted to the climatic extremes of the Chilean High Andes. It has been thought of as impossible to keep long-term and propagate in captivity. If a number of key parameters, such as a substantial decrease in temperature at night, a wide temperature gradient during the course of the day, proper air exchange, high light intensity with UV-irradiation, and cold hibernation, are taken care of, the species can be kept in a terrarium for a period of at least twelve years, however. Reproduction under terrarium conditions was successful as well and is reported on here for the first time. Two females gave birth to one and three young, respectively. Data are provided on the number per litter and sizes of neonates, and courtship behaviour is detailed. A unique observation revealed similarities between its reproductive behaviour and that of Uromastyx and Phrynosoma, respectively, which have not been described before.
