The
Sun Snake
The
sun snake, Crotalus solis, is
a close cousin of the rattlesnake, and is found all around the
southern U.S.A., as well as northern Mexico. The well-versed
snake-admirer will recognize its three distinctive horns, which it
uses to pinpoint temperature fluctuations in its surroundings.
Like
all snakes, and reptiles in general, the sun snake is cold-blooded,
meaning that it has no means to autonomously regulates its
body-temperature. Unlike other reptiles, however, the sun snake does
not go from sun to shadows in order to maintain an optimal
temperature. Instead, it will always seek out the hottest places it
can find, and use the increased temperature to drastically accelerate
its metabolism. Hence its name.
This
peculiar behavior has puzzled researchers for some time, since the
uncontrolled
increase in temperature can lead to internal damage, and, in some
cases, death. It was only recently that doctor Edward Visper, of the
California Institute of Slithering Stuff (CISS), has found the
biological reason behind this strange habit.
Contrary
to what we thought, it is only female snakes that seek to drastically
increase their temperature, and only once they carry fertilized eggs.
The increase in temperature allows them to speed up to development of
the embryos drastically, and thus provide their offspring with a
jump-start into life, which greatly improves their chances of
survival. The occasional death, or internal damage, is offset by the
evolutionary advantage to their descendants.
The
sun snake has always fascinated the native people of its habitat, and
a number of indian tribes in the region reference it in both their
customs and believes. Due to its extreme aggressivness when it is
heating up, as well as the increased potency of its poison, most
people have seen it as an emissary of the sun, representing
the anger of the star. A few tribes have gone further, and see the
taming of a heated up sun snake as a rite of passage for their
shamans, who thus demonstrate that they can quell nature's fury with
their powers.
In
recent years, due mainly to the higher fluctuation in temperatures,
sun snake populations have become instable, rising rapidly after hot
summers, and falling drastically during cold ones. In addition,
recent heat-waves have driven the animals into a frenzy, making them
extremely dangerous. We all remember the horrible tragedy of Clarkson
Elementary School, where a class came across a sun snake during a
hiking trip on a particularly hot summer day, and fourteen students
where bitten by the frenzied animal, nine of whom later
died from the poison.
