Captive Care of Monitors
Extract from A Little Book of Monitor Lizards © D. Bennett 1995. Viper Press, UK

There are very few records of the longevity of monitor lizards in captivity (Flower 1925, 1937, Snider & Bowler 1992, Bennett 1994) and virtually none of their lifespan in the wild. The record appears to be held by the Taronga Zoo in Sydney, where a Komodo dragon was kept for 24.5 years. The animal was adult when acquired, and a total lifespan of about 50 years has been predicted for this species (Auffenberg 1981). The Tel Aviv University Zoo maintained an adult desert monitor for 17 years, and estimated its age at death as at least 25 years. Other large monitors lizards are recorded as surviving for 20 years or more in captivity. Unfortunately there is much less information available on the lifespan of the dwarf monitor lizards. A female spotted tree goanna kept at the Basel Zoo in Switzerland was still laying eggs after 20 years in captivity (Bennett 1994b). Of course, the reported figures tend to be exceptions rather than the norm but they do indicate that a life expectancy of at least a decade is not unreasonable and that many specimens of both large and small species can live for at east twice as long. Monitor lizards therefore, although they do not attain the great ages recorded for crocodilians and chelonians, are amongst the most long lived of the squamates. Considering that most species can attain sexual maturity within three years it can be seen that the reproductive potential of these animals is enormous and that females of the more prolific species may be able to produce more than 500 eggs in a lifetime.

Savannah Monitor Book

 

Our pet-owners' guide to savannah monitor lizard is the first ever written by people who have studied the animals in the wild and bred them in captivity. There are at least seven books in print about the savannah monitor, but we think this is the only one worth reading! Last few available

The Butaan Project
Butaan are Obligate Frugivores!
An obligate frugivore is an animal whose diet throughout its range consist largely of fruit. Other obligate frugivores in the Philippines include flying foxes, hornbills and other birds. The butaan is much larger than any other obligate frugivore in the Philippines and had a much more restricted diet; on Polillo the diet of adult butaan consists almost entirely of eight species of fruits and two species of snails.
