Bosc or Savannah monitor

Other Species or Phases this Care Sheet May Cover:

Bosc or Savannah Monitor

Sexing and Characteristics:

Sexing most monitors can be tricky until they are sexually mature. With the Bosc monitors, located at the base of the tail in a male you will begin to notice two hemipenial bulges as it matures. The females will have lumps also but the bulge will generally dip in on the sides of the tail were as the males protrude. The most accurate and safe way would be in my opinion to observe the animal when it defecates or urinates. Usually this will be accompanied by an eversion. You can also force an eversion but I do not suggest it (I believe some people refer to this as weenie pinching)

Mostly Active During:


Substrate and Water Needs:

In the wild Bosc monitors have a variety of substrates to choose from but can usually be found in farmers fields down inside their borrows. In captivity I have kept them on sand, cypress mulch, and soil, I suggest the soil as it has bacteria�s in it that will assist in keeping the enclosure clean (soil from outside not store bought). Also soil will hold a borrow along with humidity. Cypress will hold the humidity but as for holding a borrow it is not going to hold one not long anyway. Provide a water bowl large enough for the animal to soak it�s entire body.

Lighting and UVB:

UVA/UVB is not necessary with this or any monitor species. I use GE outdoor flood lights with excellent results.

Temperatures and Humidity:

Basking temps of 100-110 should be provided for the Bosc with an ambient air temp on the cool side of 80-83 humidity can be achieved by just adding water to the substrate when needed (if your evaporation rate is high you will need to add more water more often) Use the water throughout the enclosure but not enough to flood any burrows. This should give you a fairly good humidity level.

Heating and Equipment:

I use GE or equivalent bulb for heating (a basking spot that will be within the 8-9 inch mark away from the bulb should use a 50 watt if a foot away go up to a 75 watt. This should give you an almost perfect basking temp. I use porcelain light fixtures and electrical boxes to assemble my light fixture it cost me about 3 dollars a fixture. Ceramic fixture with domes can be purchased from any pet shop fairly inexpensively.

Caging Provided:

Caging is important a hatchling can be started in a 15-20 gallon tank. As for adults there should be at least one square meter provided for an adult pair. 3/4 inch plywood can be used to build adequate caging 4x4x4 is sufficient with multiple basking and water areas. I would suggest if you want multiple animals by them at the same time don�t try to introduce a newbie into an enclosure with an existing resident.



Description of Diet:

Hatchlings do excellent on a diet of roaches, crickets, and pinkie/fuzzie mice. adults should be fed a diet of almost exclusively rodents. For both young and old ground turkey is OK as a treat maybe twice a week but not as a staple. Remember Bosc monitors are prone to fatty liver disease. If basking temps are kept high enough this should not be a problem. Just keep an eye on its weight and if you notice it is getting heavy slow down the feedings.

Supplements, Nutrition and Usage:

I swear by Miner-All produced by sticky tongue farms.



Some Words on this Species:

There are a lot of questions as to taming this species (more so than others) so I will tell you how I go about it and have gone about it for years. First things first people are under the impression that the baby they just got is mean, well it almost certainly has the complex that I like to refer to as the "OH MY GOD HE IS GOING TO EAT ME "complex. Remember you are 100 times the size of this little thing and it is scared for it�s life. Try opening the enclosure and placing your hand inside don�t just grab it because the above mentioned complex will take effect. Give it time to come check you out, if you do this with no results then the animal is being anti social and you will have to pick it up against it�s will. A baby Bosc does not hurt to get bit by but the first instinct is to drop it throw it or just place it back in the enclosure and forget about it. If this is done then you will have a problem because it will get bigger and meaner. Let it bite if it wants to sooner than later biting will be no more fun and as quick as the first bite you will see the last. In short if you let the animal (any animal) know that it can get what it wants by biting then you are never going to get it to stop.
