Reptiles - Snakes of the Rainforest
Australia
is known for its large number of extremely venomous snakes but we
have at least 10 python species as well. The largest snake in the
country is a very common Wet Tropics 'celebrity' which is often
seen by visitors and which frequently visits the area's human inhabitants,
especially those who keep domestic animals.
The Amethystine Python (also known locally
as a Scrub Python or Scrubbie) has been confirmed at 7 meters long
but anecdotal accounts suggest that larger individuals have been
seen. It is very distinctive with a tan diamond pattern along its
length and is often seen crossing roads in the rainforest at night.
People living on the edge of the bush or people
keeping birds often report them in their yards. Pythons feed on
warm-blooded animals and have heat-seeking pits in their jaw to
locate their heat-emitting prey. Domestic pets such as small dogs,
cats, chickens and parrots are frequently an easy target of the
Scrubbie and aviaries must be 'snake proof' to protect their residents.
The Amethystine Python (Morelia amethistina) usually has a docile nature however, it is not advisable to approach
or attempt to handle any snake no matter how tame it might seem.
A bite from this snake could result in a severe wound that would
probably bleed profusely. Additionally, a python's body is almost
entirely muscle so a large individual is extraordinarily powerful.
Once coiled around your body, the combined strength of several people
might be required to remove it.
Mention venomous snakes and the typical response
is that you're talking about a dangerous snake - but that is not
necessarily so! There are two types of poisonous snakes in Australia.
One group is called the Elapids and these snakes distribute their
venom through their front fangs. The other group is the Colubrids
and some of these also have venom glands but the toxin is dispersed
through fangs in the back of their mouths. To receive a dose of
the Colubrid's venom, you'd basically have to stick your finger
down its throat!
The
Brown Tree Snake is often seen in and out of the forest at night
- it is sometimes called the night tiger. The Brown Tree Snake (Boiga irregularis) is normally about 1.4 metres (4 ½
feet) long and it is not dangerous to us - but birds, small mammals
and lizards would not like to meet one.
A group of Australian snakes that we need not
fear but should have a healthy respect for and that is the Elapids
- the front fanged snakes. Even though this group has the capability
to be harmful, the majority are not. Only a few of these have aggressive
or easily excitable dispositions. It is a good rule of thumb for
any snake you encounter to leave them alone and just admire them
from a distance.
Little
in size does not necessarily mean little in threat. The Small-eyed
snake is shiny black above and cream or pinkish below and it's only
about 50cm (20 inches) long but it should still be admired from
a reasonable distance. The likelihood of the casual visitor seeing
one in the forest or heathland is not great however, as this snake
is shy and nocturnal. It normally lives under rocks or logs so be
observant when climbing over these during night bushwalks. This
Small-eyed Snake (Rhinoplocephalus nigrescens) bears live
young - usually four or five and its favourite food is lizards.
