  1. Breed reptiles in captivity: Lizards

    A study in 1980–1986 [location unknown] (Chippindale 1991) found that Timor Monitors Varanus timorensis similis bred successfully in captivity and produced hatchlings in two of three years. A female produced one clutch/year of five eggs for three years. Zero eggs hatched from the first clutch, and two eggs from both subsequent clutches hatched successfully (40% hatching success). Incubation periods ranged from 121–140 days, and the four hatchlings survived for at least 2–3 years. In 1980–1981, a wild-caught female and three male monitors were housed in a glass fronted terrarium (195 x 36 x 60 cm) with a newspaper substrate, branches and rocks. Temperatures were 26–30°C during the day and 20–23°C at night. Eggs were moved to a 40 litre aquarium containing 1 cm of water and placed on a raised aluminium screen. The temperature was maintained at 28–30°C, and humidity was 90–100%. Hatchlings were housed individually in 60 litre aquaria with a newspaper substrate and cardboard tubes.
