NAKE, the name itself sends a chill
down the spine. Whether we like
them or not they are a part of our
age-old culture and heritage. In most
cases they depict negative forces.
Even quotes and proverbs in different languages have given them a special place.
There may be very few animals with more
enigmas associated with, than a snake. Even
today when intergalactic communication is
becoming a reality, people find it hard to
believe that snakes are just like any other
animal around us. Myths and superstitions
have made them more then just an animal.
One of the most popular of all these myths
is the concept of icchadhari nagin wherein
a snake by its wish can turn from itself to a
human being. Interesting! Philosophically
humans are the greatest creation of God.
Now if a snake can switch between itself
and human being, it should have been the
greatest creation ever. Scientifically, evolutionary biologists in the likes of Darwin and
Lamarck would have turned in their graves
seeing such a fast rate of evolution. But the
fact is they are just another vertebrate occupying a place in animal kingdom, with may
be just a little exception in the form of venom that a few of them produce.
Snakes are a very interesting group of animals which are believed to have evolved
from lizards like life forms more then 100
million years ago. Those lizards like forms
slowly evolved to what we know today as
snake. The first thing we notice in this evolution is the loss of limb. Let us think of
ourselves without limbs, it’s just scary! But
for snake it was rather a boon. Now it could
get hold of its prey into those burrows and
holes where its previous form could not,
because their limbs usually got stuck! Gradual evolution has made them master hunters. They can swim in water, crawl on
ground, climb tall trees and some of them
can even glide in air. Also they do not have
ears like their lizard cousins. This means
that they are deaf to the air borne sounds.
But what about those spellbinding street
snake shows, where the snake charmers
make the snake dance to the tune of its
been. Snakes actually cannot listen to any
of those tunes which have a far fetched effect in our own Bollywood. The snake rather
focuses on to the movement of the arms
and the been of the charmer and just responds to those movements. Rather snakes

taste their environment. The forked tongue
of the snake is its most important sense
organ that collects the scent particles around
it. These scents are then decoded in an organ attached to the roof of the tongue,
called the Jacobson’s organ. That’s why we
see the snake flicker its tongue. By doing
this they keep a track of their surroundings.
Though some snakes have acute vision, but
in most cases they are no match to us in
seeing this beautiful world. In addition to
these, some snakes have an additional sense
organ in the form of ‘thermo receptor pits’.
These are either located on the upper lips
or between the nose and the eyes of the
snake. Through these pits they can gauge
the slightest of temperature fluctuations
around them, thus enabling the snake to
strike with surgical precision, even in complete darkness.
Snake are ‘ectotherms’, meaning that they
cannot regulate their body temperature as
we do. That is why they hide during winter.
Another queer character of snakes is that
they regularly shed their skin. This is because they grow continually; and the old
cover can no longer hold them.
Perhaps the most important thing regarding the snakes is their capacity to produce venom. This venom is produced in
small sacs called venom glands present in
the posterior part of their upper jaw. When

a snake is excited or feels threatened it
lets lose this venom which travels from
the gland to the fangs via venom ducts.
Fangs are actually just the enlarged teeth.
A typical fang is hollow from inside,
through which venom runs out when an
injection is made. Fortunately, majority
of the snakes are non-venomous and rather harmless as opposed to our prevailing
belief. Our irrelevant fear associated with
snakes is one of the most important factors in the way of their conservation. For
most, all snakes are venomous. But the
fact is in India, only about 20% of all
snakes, except those living in sea, can
cause a fatal bite to humans. Even more
interestingly, most of them are forestdwellers and less than 7% of these venomous snakes come in any type of human contact. The snake venom is a complex mixture of proteins and inorganic
ions. The venom once administered in the
body of the victim will act according to its
composition. The venom of cobras and
kraits are basically neurotoxic in origin,
wherein they block the nerve impulses and
generally the victim suffocates to death,
as the nerves feeding the diaphragm with
impulses generally stop working. The ef-
fect of envenomation can be experienced
quickly, maybe within an hour of bite. For
others like certain vipers producing cytotoxic venom, the effect may take time to
set in. Bite from this type of snake generally destroys the tissue and causes necrosis. In this type of bite even if the life is
saved, the victim may have to go for organ amputation.
Fortunately, the answer to these snake
bites lie in the snake venom itself. The
antivenom is the only medication available
during a venomous bite. The antivenom is
prepared from the venom of the snake itself. Also the venom has other medicinal
implications. Studies show that snake venom may slow down tumour growth. The
anticoagulant property in the venom of
some snakes may help treat various heart
ailments. Snake venom can also help formulate pain-killers thousand times more
potent than morphine. Snakes, in general, are also important. They maintain balance in the ecosystem. It reminds me of
Janmastami festival celebrated in Mumbai,
where devotees form a human pyramid with
a goal to break a dahi handi above them.
Now consider removing any of the devotees from the pyramid except the top one.
What will be the outcome? Yes, the whole
structure will collapse. The snake here is
equivalent to any of those devotees, re-

move the snake and the whole ecosystem
will collapse. Also snakes feed upon small
mammals like rats and mice which are a
menace to farmers.
In India most of the snakes are protected
by law but practices like snake charming,
trade of snake skin and malicious killing of
snake still prevails. Most of the venomous
snakes used by snake charmers are either
defanged or the whole venom gland is removed, and ultimately the snake dies a slow
and painful death. Here we can play a vital
role by not participating in these types of
inhuman displays. But, there still remains
an ethical question to be answered. What
will the snake charmers do now? They were
doing what they knew the best. The answer lies with the Irulas of South India. The
Irulas now have taken up the work of venom extraction from the snakes with the help
of local agencies. Their knowledge on
snakes is again earning them their bread,
but this time for a noble cause, for production of antivenom. Another problem is the
snake-human encounter itself. In most cases, the former has to lose its life because of
our misconception regarding them. Fact is
snakes only bite if provoked or cornered, or
else their general instinct is to avoid us. They
are rather more afraid of us than we are of
them!
More than hundred species of snakes are
reported from the Northeast India. About
25 odd species of snakes can be found in
and around Guwahati itself with checkered
keelback (dhora saap), common water snake
(meni saap), common wolf snake (maruli
saap), striped keelback (bamuni saap), trinket snake (nilaji gom), redneck keelback (batraj), python (ajagar), monocled cobra
(chokori pheti), Indian rat snake (hulaberia)
being the most common ones. Since the
Northeast is a biodiversity hotspot, more
research will certainly reveal new data regarding the snakes. With more knowledge
of facts regarding snakes the irrelevant myths
and superstitions among masses will slowly
die out, thus helping the cause of conservation of this misinterpreted animal. Whatever it is, we still remain the greatest creation
of nature ever, but why? It’s just because if
any organism has the power of reorganizing most of the aspects of nature for a better tomorrow, it’s ‘us’. If we do not take
care of our earthly cousins, who will?

DOLL DOMINATION, BY PUSSYCAT DOLLS, UNIVERSAL, RS 395
LOS ANGELES glamour babes the Pussycat Dolls’
second album, Dolls Domination,
seems to show some sort of a
character by having songs of loss
and love. Reflective of the quintet’s
growing maturity, this dance popheavy album is also helped in
attaining its quality by some top
international artistes. While the
Pussycat Dolls make simple pop music for the ears of
the masses, they tend to sell their brand of music through
their glamour quotient. That said, the highlights of this
revised album definitely are the hit singles Jai ho (you
are my destiny) - AR Rahman & Pussycat Dolls, When
I grow up, I hate this part and Bottle pop feat. Snoop
Dogg (Punjabi MC remix). You folks may also try out
catchy tracks such as – Whatcha think about that feat.
Missy Elliott; Out of this club feat. R Kelly/Polow Da
Doon; Who’s gonna love you; Magic; Halo; In person; Hush hush; Love the way..., Painted windows,
etc. While Doll Domination may just remain a title,
their music may still appeal to many a music buff!
ARZIYAN, KAILASH KHER HITS, T-SERIES, RS 149
SOULFUL and Sufi have become synonymous with
Kailash Kher with the diminutive
singer’s bulk of works belonging
to that genre. This album’s title,
Arziyan, amply indicates the Sufi
spirit of establishing a communication with the Supreme Power.
Characteristic outcome of a pure
soul, Sufi songs show the quality of serene sweetness
and this can found in abundance in this compilation
(also featuring Sunidhi Chauhan, Richa Sharma and
Amitabh Bachchan). Serious music lovers here get an
opportunity to do some soul searching through gems
like – Arziyan, Ya Rabba, Mere maula, Toot gaya, Jhuki
jhuki, Kawana janam ke badla, Ud ud jaye, Barf khushi
hai, Chak lein de, Chal rahi hai saanse, Rama o Rama,
etc. Get a feel of the magic moments when Kailash’s
earthy voice attains a touch of divinity!
I LOVE BHANGRA, COLLECTION, SONY MUSIC, RS 175
POPULARITY of Punjabi pop may be past its prime,
but the power/punch of its infectious rhythms definitely has an
enduring quality. This has been
proved time and again by
numerous hits charts featuring one
Punjabi variety number or the
other. Now this 2-CD album containing ‘the definitive Bolly
Bhangra blowout’ attempts to cash in on this very
craze for Punjabi pop. Many of you would end up saying
‘I love Bhangra’, after tuning in real HOT hits such as –
Maa da laadla & Desi girl - Dostana; Jee karda - Singh Is
King; Dhol wajda - Kailash Kher; Glassy - Sona Family;
Let the music play - Shamur; Saawan mein... - Mika;
Akhiyan udeek diyan - Jinx; Boot polishan - Gurdaas
Mann; Ishq & Gal ban gayee - Sukhbir; Mundiyan tu... Punjabi MC; Mitraan di jaan - H Dhami; Sexy naughty...
Bhangra mix - Tata Young; Akhiyan teriyan - Kaal; Pretty
woman & Maahi ve - Kal Ho Na Ho; Say shava - K3G;
Rang de basanti - RDB; Kaava... - NC Karunya, etc. It’s
