The
Mhadei Research Center has been conducting studies on the Herpetofauna of the
Chorla Ghats area since 2004.
The
Chorla Ghats area is part of the Mhadei Bio region and covers the three states
of Goa, Karnataka and Maharashtra.
On
5th July 2012 night at 10.30 pm, a Malabar Pit Viper snake
(Trimeresurus malabaricus) was observed approaching a foam nest of a Malabar
Gliding frog
(Rhacophorus
malabaricus) on a branch of a Kumbh tree( Careya arboreya) . A female of the
Malabar Gliding frog (R malabaricus) was seen besides the foam nest in dormant
state on a leaf of the same tree.
At 11.05 pm the Malabar Pit Viper caught
the female R malabaricus, at mid section of the body and proceeded to swallow
it headfirst. The process took 40 minutes approx after which the snake moved
across to another branch of the same tree.
Endemic
to the Western Ghats of India, the Malabar Pit Viper has highly developed heat
sensory thermo receptor pits between its nostrils and eyes, which enable it to
locate and strike at a prey even at night. They also enable the viper to sense
temperature changes of up to 0.001 degree Celsius and strike with pinpoint
accuracy. That’s another reason why it is known as the pit viper.
The
Malabar Pit Viper, which feeds exclusively on lesser life forms like lizards,
geckos and juveniles of birds, occupies an important niche in the forest
ecosystem and is rather shy in temperament unless it is threatened. Its venom
is mildly toxic to humans and its bite has known to cause swelling and pain,
for up to 48 hours in some cases.
Very
little is known of the behavior and biology of this endemic pit viper and the
observations made could be an addition to the understanding of the seasonal
selective prey base of this species.
The
Malabar Gliding frog is a flagship species of the Western Ghats. Its status is
classified as NT (Near Threatened) by the IUCN Listing of 2002 and is
threatened due to habitat alteration and exotic monoculture plantation all
throughout its range.
Its
red webbed feet, green coloration and other field identification details that
were confirmed with photographic evidence identified the amphibian.
The
area of the incident was above a water body where dominant vegetation included
False Guava, Sting nettle, Citrus sp. and Bamboo. The vegetation surrounding
this area is typical of a secondary forest ecosystem typical of the region.
The
height of the tree from the ground where the snake caught gliding frog is 2.5
meters from the ground and the altitude of the place is 644 msl.
The
lat/longitude, hygrometric data and other details were recorded along with a
few record shots from a distance to avoid disturbing the pit viper
The
skies were partially cloudy and the temperature was 28 degrees centigrade.
