Leaping Lizards! The Hall Monitor May Not Be What You Were Expecting!

 

My experience with the Western Pacific monitor lizard, Varanus indicus--also known as the mangrove monitor--has been over 12 years of living on the Western Pacific island of Guam, with side visits to Saipan, Tinian, Rota, Belau (Palau) (The big lizards have been frequently shown on CBS's "reality show"--"Survivor-Micronesia"), Chuuk (Truk), and Pohnapei. I've seen the 12-inch long juveniles near our home, and have encountered the "big ones" in the mangrove swamps and tropical forests of Guam, Palau, and Saipan.  When you are face to face with a large lizard that doesn't want to back down and go away, it's a whole 'nuther feeling you get in your tummy.


Also, after working with these critters for a bunch of years, I went and watched the movie Jurassic Park--it was like watching a "reality show"!

Monitor Lizard Versus Crocodile and Birds... 

But still gets a breakfast of eggs!

Looks like this monitor is an Australian "goanna" and the croc is an Australian Saltwater or Estuarine Crocodile--also called 'Saltie' or "Indo-Pacific Crocodile"...Crocodylus porosus (SCHNEIDER, 1801)

Monitor Lizard vs. Croc

For the monitor lizard it's no easy task snatching crocodile eggs. Especially not when you're up against mama croc and her feathered friends, dikkop birds. http://video.nationalgeographic.com/video/?source=4001

A Different Kind of Lizard 

These critters aren't like the iguanas and other lizards...They are "Old World Lizards"

Although lizards in general have received the greatest attention among reptiles with regard to population dynamics, most of these studies have been limited to specific life-history aspects of a few species within the families Iguanidae and Agamidae. These studies have dealt with mostly temperate environments; quantitative studies in the tropics have not been undertaken. Varanids are tropical and subtropical old-world lizards. And because they attain large sizes, are difficult to maintain in controlled experimental environments, and tend to have low population densities in the wild, the monitors have not been the subject of extensive ecological studies.

Carnivore, Omnivore... hey, when it's got a hold of your foot, does it matter? 

The Pacific monitor lizard Varanus indicus (Daudin) or mangrove monitor lizard has a major predatory role in Micronesian forests (Western Pacific Ocean Islands)--it feeds on reptile and bird eggs, land snails, rodents, insects, crabs, small lizards, and carrion. Evidence in the research library of the University of Guam Marine Laboratory also indicates that the monitors also feed on fish--fish specimens preserved in the research library had been regurgitated by a cornered monitor in Palau. However, little ecological work with this animal has been done. Existing studies of Varanus indicus involve aspects of the monitor's feeding habits and food preferences and the lizard's utility as a rat control agent. But since rats are generally nocturnal (active at night) and since the monitors are active during the day, this application for "biological control" is a bit "misguided".

And their bigger relatives, the Komodos, don't need a male to have fertile eggs! 

If just one escaped into the boonies near your house... sounds sort of like a movie about *big* lizards...

Varanids (and other families of lizards) have been assumed to have life-history and population characteristics similar to those of the Iguanids and Agamids. However, Dr. Walter Auffenberg, an expert in reptiles and particularly the Komodo Dragons, has shown in comprehensive studies that the social and feeding behaviors of Varanus komodoensis (Ouwens) differ significantly from those of Iguanids and Agamids. There is only one genus, Varanus, in the Varanid family, and thus there are many physiological and behavioral similarities between all members of the family Varanidae. Recent news: I just heard that Dr. Auffenberg recently passed away. I had corresponded with Dr. Auffenberg when I was working on my MS in Biology and studying these animals. He'll be greatly missed.

Monitor Lizards--a throwback to the dinosaur days.... 

On Guam, I've encountered monitor lizards in mangrove swamps as well as deep within the limestone forests. Every time it has been an exciting experience--even if a bit disconcerting. If you surprise one, it usually hisses and makes a more threatening posture to try to scare you off (and they usually are good at that--especially the big ones! If the hissing and defensive posture do not scare you off, the monitor will try to scramble noisily through the underbrush.

If in a dense tangle of roots in a mangrove swamp or in the thick underbrush of a limestone forest, the monitor lizards can easily evade capture through the tightest maze and quickly avoid any further encounter.

If cornered, however, they can become quite formidable. Their saliva contains a nasty mix of decaying tissue and bacteria (and now scientists have discovered that they may also have venom glands that produce an addition to the toxic brew in their mouth). When a monitor bites any prey, the prey succumbs eventually to the toxic saliva--anaphylactic shock sets in--and then its wound puts off a stench from its decay such that the lizards will be able to find their kill, dead or still alive (but barely).

Obviously, you do not want to be bitten by a monitor--in particular the Komodo Dragons--but any monitor can cause some serious damage. Their teeth are sharp and serated... used for ripping flesh. They can take a critical chunk of flesh when they bite.

So it's best to avoid being bitten. Although they may seem slow, they can speed to 30 miles per hour in short spurts. They can also lunge with their long necks. So, if you have one in your close proximity, take care around them. They can be relatively docile indoors, but if they get outdoors in the sunlight, they can become irritable and more aggressive.
