An Email correspondence from Raymond Unsaid, a New Guinea resident, remarks
on questions raised about the crocodile monitor.
What is the salvadorii's diet in
I have observed one digging and eating megapode
(Megapodius spp.) eggs from itís mound at headwaters of the Aramia, near Awaba,
some 20km from the nearest town, Balimo. Western Province. June
Within the same year hunters came across a wild juvenile pig being
killed and intestines removed, believed to be by a salvadorii, I went to the
site and observed trails of the lizard all around the location. Small
cassowaries and birds are also preyed by the lizard.Rodents and wallabies make
up the rest of its meal.
What is the maximum size they have
According to literature I have viewed, the highest
recorded length was 4.7 meters or 470cm Snout to tail, this record was taken by Professor Popel
in 1987, he than placed it in PNG Museum, the last time I visited the museum in
2001, I couldnít see a Varanus of this length. Stories from hunters in Western
province who live a predominantly hunting and gathering lifestyle to date, have
described much longer sightings while out hunting. A very gifted hunter named,
Laule Daiki, who I have come to know very well and have lived with him in the
village for 4 years in my trips to the forest area did several sightings and
killed some which he normally brings for the family dinner. Most villagers in
Western, Gulf, the Sepiks and Indonesia part of New Guinea have made kundu drums
with itís skin. From collections of skin in the villages, size and length can be
What is the actual geographical
distribution on new Guinea and the surrounding islands?
have seen drums made of skin hunted in East and West Sepik, Gulf, all of Western
Province and Central. In literature, it is confirmed to be in all these areas as
well as Cape Vogel peninsular.
Are there any different
variations on the island from place to place, or is the size and colour
From my observation the reptiles that occur along the
mangrove look slightly different in colour than the ones in mid montane
rainforests (not to be confused with the mangrove monitor,
Is there a difference between the behaviour of the
young and adults?
I am yet to meet a young in the wild so I
cannot give you a precise difference here. What I know however is that, it is a
good swimmer and climber, there could be variations in the way they feed, climb
and swim/dive between young and adult salvadorii.
aquatic/terrestrial/arboreal are they?
They are good
swimmers, it lives almost away from any contact, most hunters meet it while
pursuing deer ,pig or wallaby along the same trail. Most of its trails can be
seen around megapode nests (Megapodius spp). I have sighted trails along two
nests while in the jungles with Laule Daiki the hunter. A good time to video
tape it will be during nesting season of megapode birds. They spend most of
their time on land/trees and say 30% around water.
What are the
extremes of temperature they actually experience in nature, e.g. How much cold
can they handle?
Can only handle New Guinea lowland temperatures I
Are they solitary or do they pair
Havenít seen a pair in the wild, I presume they
probably move in pairs as hunting and feeding requires a lot of work and feed in
the wild is rare. However most hunters I confer with tell me they have sighted
When and where do they lay and how many eggs?
How long for hatching?
I havenít seen a nests so I cant
give you much info on this. According to Litereture Iív scrambled across they
lay about 5 to 7 eggs percluts and there could be 2 or 3 clutches per
What is their relationship to the other animals in the
forest and the indigenous people?
To other animals, they are
mostly feared. They are very good runners and can hunt prey effectively. All
hunters and village people tell me that when an animal is killed by a
salvadorii, it uses its sharp claws to reap open the ribs of larger animals and
remove only the internal organs to eat. On several occasions villagers stumble
across dead pigs and deer with open guts unexplained, thus they believe a
salvadorii had just killed and ate internal organs.
Most locals cannot tell
the difference between each Varanus species, all they see is a giant lizard
which at times they have one name for all species of Varanus, for instance the
Gogodala tribe call it ďPasiyaĒ
Generally people fear salvadorii more
than any animal in the jungle as such hunters (Daiki,pers comm.) do not go
beyond a certain limit when out hunting. People eat the meat, eggs, use the skin
for ceremonial kundu drums,apart from this it is revered as a sacred ancestral
reptile depending on each tribe.
