The Formeleon
The formeleon, Brookesia
forma, is one of the smaller
members of the Chamaeleonidae. At barely two inches when fully grown,
and unable to change its green color in the slightest (except during
mating season, when males are of a slightly lighter shade of the same
color), the formeleon might, at first glance, look like a rather
uninteresting species of chameleon. At second glance, however, it
often doesn't look like a chameleon at all.
Indeed,
unlike its cousins, some of which change color to camouflage
themselves, the formeleon changes its form to hide its presence. From
a thickish leaf to a stout bough to a roundish fruit, the formeleon
easily blends into its environment, invisible to both prey and
predator. This ability is due to its extremely flexible joints, which
are also present at the base of its ribs, as
well as its unusually elastic skin.
This morphological oddity, unheard of in any other species of
vertebrates, allows it to shift
through an almost infinite number of shapes. In some extreme morphs,
it can even change the overall volume of its body.
Due
to the constraints its form-switching imposes on the size of organs,
its eyes and tongue are much smaller, relative to body size, than
those of its cousins.
When
scientists first discovered the formeleon in 1846, in Madagascar,
they thought rather little of it, since its unvarying color often
allowed them to spot it easily, even if the shape would have
otherwise camouflaged it. They saw its shape-shifting capabilities as
an unusual, yet impractical ability. However, as it became apparent
that most of its prey and predators are color-blind, the formeleon
was seen in a new light. In addition, the first few individuals had
been found on or near the ground, where its color stood in stark
contrast to the brown of the fallen leaves and stout tree trunks
around it. But in recent years, it has been proven that formeleons
live mostly up in the foliage, where it is nigh on impossible to
spot, both form and color being used to blend into its surroundings.
In addition to Madagascar, the species has been discovered
over most of Africa, as well as southern Asia. The reason why it took
so long to realize
the extent of the formeleon population is presumed to be precisely
because its camouflage is so effective.
In
both African and Asian culture, the formeleon holds a special place.
It is believed that formeleons are what originally inspired shadow
plays. Originating from India, where the species is common, they have
lost their connection to the animal as they were adopted by the
chinese. However, if one places a formeleon in front of a fire, it
changes its shape continuously, in an effort to blend into the
ever-changing form of the flames, which causes its shadow to morph
with it.
In
Africa, this same ability helped it become a mythical creature which,
depending on the tribe, might warn of impeding danger, conjure up
demons, or both. For this reason, it is often depicted in tribal
paintings, as well as on weapons or at the entrance to residences,
either to ward of evil, grant inhuman abilities, or for luck.
Like
all chameleons, the formeleon's diet consists mainly of insects,
which it catches when they venture close, unaware of the danger.
Deforestation and
environmental pollution are the main cause for the decline of the
formeleon population, which has been accelerating at an alarming rate
these past years.
