Advanced Dragon Description
The information presented here contains all the theories that I have
been offered (and for a large part thought of by myself) during all
these years. They explain how a creature such as dragons could be
living in our world without breaking the fundamental laws that rules
our universe. Here you will find no magic but only a person with a
good knowledge of science pondering the countless possibilities of
biological structures and organisms.
General Physiology
The dragon is a homoiothermic reptile. In other words, he is a
warm-blooded creature and his body temperature is controlled
internally. This characteristic enables him to adapt to the different
climates of his very extensive habitat and to maintain his activities
both day and night throughout the year, as he is not dependent on the
warmth from the sun like the other reptiles. The dragon generally has
wings, and his bones are hollow, for lightness. There are dragons,
usually ancient survivor from the distant past, with stumpy legs and
no wings. These rare survivors of a remote era are intelligent and
fairly aggressive, and belong to a single species known as "worm of
the deep", a species on the verge of extinction. This creature lives
for a very long time. There are records of dragons who have lived for
five hundred and even a thousand years, but there are no knows cases
of dragons who have died from old age. On the other hand, they died
from accidents, certain diseases, or as a result of the actions of
their most relentless enemy: MAN.
The Skeleton
The dragon is the largest known flying creature. To maintain his
enormous bulk in the air, his physical structure has had to be
different from that of other reptiles whom many persons inaccurately
associate dragon with these.
His wing bones fit on to broad shoulders which support the powerful
wing muscles; these require an extraordinary articulator system
unknown in other species. The bones were tougher than reinforced
concrete and much lighter.
It is important to note that the bones of a dragon are hollow like
bird reducing their mass, scientifically: any creature with the
physiology of a dragon can flight well and at great speed.
Picture of a 3D dragon skeleton is Under Construction. Coming soon
with maybe a detailed 3D muscular system, we continue work on it.
The Muscular system
The dragons muscular system is one of the most fascinating... and one
of the most complicate. We can evaluate the power in the bite of a
dragon to put to an average of 2 ton per cm cube (in comparison it
could easily gnaw steel).
As a matter of fact, dragons are very powerful. Their leg and "arm"
can support great charge without much difficulty but this only applies
on ground movement because in the air, a dragon could not maintain
more than half of is weight for a long period of time.
If you have vision keen you probably notice something at the looking
of the muscular picture and the skeleton picture... with the
observation of the front and the rear paws, I come to the conclusion
that dragons COULD NOT run, their muscles of the leg and arm were not
developed for this matter. This doesn't means they could not walk,
this only means that they could not reach great speed at ground. (Take
in consideration that dragons come in so much variety that it could be
possible for a dragon to run but not those who have the similar
structure of the picture above).
The Scales
The dragon's body is completely covered with tough, shiny scales.
Dragon usually doesn't have this scaly armor on the neck or stomach,
possibly due to his habit of burrowing underground, not all
draconologist are agreed about this. To protect his "soft" abdomen (at
least weaker than the rest of his body) the dragon often wears jeweled
breastplate. Using his saliva, which has powerful adhesive properties,
and which he secretes on an empty stomach, the dragon often sticks
precious stones on his neck and stomach, for protection as well as
adornment.
The scales are pentagonal, and shaped like a teardrop, with two long
sides and two shorter ones, and a very short fifth side attached to
the skin. The dragon can make them stand on end whenever he likes to
preen them. Remember, the dragon is a very clean creature and takes
great care always to keep his skin and scales clean and immaculate.
In their normal position, the scales overlap very neatly and, thanks
to a tiny cavity in the surface, they fit into each other to allow
perfect freedom of movement.
If we study a scale closely, we observe the following characteristics:
the innermost part is composed of a compact hairy formation firmly
rooted in the epidermis. On the hair follicle there are some tiny
glands which secrete a substance that adheres firmly to the skin.
This substance is rich in minerals, which determine the hardness and
the color of the dragon's scales. The external surface has a horny,
translucent texture, which gives the scales their habitual luster.
CROSS SECTION
The dragon does not need to sloughs off his skin like most other
reptiles, as the scales grow, they are renewed automatically, like
human nails and hair. They are not shed from the body, except in case
of illness.
FRONTAL SECTION
Wings and Flight
The wings of a dragon are based on the principle arm of any animal,
i.e. they consist of an thumb and four very lengthened fingers, the
whole connected with a membrane as we can observe in the bat. It is
significant to understand that the similar struture between the
shoulder, the arm and the hand is homologous with the corresponding
structures of the wing for the dragon (see opposite figure). It is
also important to understand that the membrane of the wing do not
attaches close to the shoulder as certain biologically erroneous
drawings can sometimes shown but near the bottom of the back of the
dragon close to the thighs.
This is very important since if the wings would be connected in the
top of the back, the dragon would fly but it would have a vertical
position (head up, posterior & tail down) that would be a serious
disadvantage for the speed and also for the maneuvrability. When the
wings are connected at the bottom of the back, the dragon can have a
horizontal position and thus the head and the tail can be used as
rudder and allows a great maneuvrability (at least, definitely higher
than the vertical position). This also allows a greater surface for
the wings (a critical element in flight).
1. The wings are connected near the shoulder.
This is the most improbable type of wing. The surface is small near
the body making the flight and even the glidding difficult, moreover
the rear of the dragon tends to "fall" toward the ground.
However, this disposition gives good results if the dragon is
hovering.
2. The wings are connected below the chest.
The wings as shown on the complete picture above is somewhat the mix
between the situation 1 and 3. There is no real mistake here, except
that situation 3 is better.
3. The wings are connected near the thighs.
This give a greater surface for the wings than the situation 1 and 2.
The long neck and the tail give balance and enable the dragons to
quickly gain or lose altitude.
This is definitively the most probable type of wings.
Coloring
It is impossible to list the enormous variety of hues that make up the
dragon's brilliant coloring, but they can be divided into three broad
color groupings:
Blues, ranging from dark blue to silver and mother-of-pearl.
Red, ranging from copper-red to dark red and reddish-black.
Greens, which include every imaginable shade of green and yellow and
even dark brown, emerald green and burnished gold.
Although these three principal color groups are not usually mixed, a
dragon's coloring is rarely uniform. In general, his scales are
several hues from one of the main color categories, with a metallic
luster which is hard to define. When the scales have a pale, opaque
appearance, it is a sure sign of ill health.
Many dragons are known by their scales, such as Ancalagon the Black,
Smaug the Golden and Spars the Green.
Dragons - David or Goliath?:
For many of you, the word "dragon" means huge, enormous or imposing
creature but out of any reasonable doubts, the facts are different
from the fairy tale. Dragons are probably small creatures (from 1 foot
to 10 feet long). For this we need to look at fundamental principle of
physics called "Physics of Proportion" or more commonly called
"Physics of Lilliput".
First, you look at a cube (1cm x 1cm x 1cm) and you decide to double
the length and you want to keep the proportion. You will have a bigger
cube (2cm x 2 cm x 2cm). The length of the enlarged cube will be
multiplied by 2, the surface will be multiplied by 4 and the
weight/volume will be multiplied by 8. For example, let say that a
bird needs to have a wing span equal to his body length to fly,
enlarge this bird ten time. There will be 100 time more surface...
However he will weight 1000 time more and since his wings give him the
power to fly and that these rely on the surface and not on the volume,
he will be unable to fly for his lack of lift power.
We have proof now that a large creature could have some difficulties
to fly, but we haven't proof they cannot exist. The second thing is
the structure of the dragon. Some persons send me theories that
dragons could have cartilage instead of bones but this could only be
possible in very small creature: The shark for example, live in water
and in water your apparent weight is much lighter than in air that
explain why an animal like this could live with only cartilage. Look
at your nose and you ears, these are made in cartilage but as you have
surely notice, this isn't very strong and it's could not support the
weight of your entire body. Now if they cannot be made with cartilage,
they are obviously made with flesh and bones but the fact with bone is
that they rely on the surface (i.e. diameter and not surperficies) to
be strong and large bone increase the mass and thus make the flight
much more difficult.
This is more realistic to say that dragons are small creatures if you
consider that they can fly otherwise, they will follow the same
principle in the structures of these huge magnificient reptiles: the
dinosaurs (in this case their wings would be absolutely useless).
(Summary of the "Physic of Proportion": The rule is simple, when you
change an object proportionally, the change "A" affect the dimension
as this: the length=A, the Surface=A2 and the Volume=A3. Eventually I
will fully detail the effect of this physics principle... until this
time, please bear with this present section...)
The Dragon's Eyes:
I think this point really needed to be cleared up since artistic
representations and sciences occasionally do not mix very well.
Dragons eyes are usually shown to be reptilian with a vertical slit
for the pupil, while somewhere else you will have a round pupil and if
you search hard you may even find dragon with insect-like eyes not to
mention the "glow-in-the-darktm" eyes with no pupil at all.
In all these view about dragons (pun intended), what is possible and
what is not, and more importantly: why?
The traditional (vertebrate) dragon eye:
The eyes come in two flavors: with a round pupil or with a vertical
slit. This is just a small detail because they both work the same way
and they both have much in common with a standard camera. The light
first pass through the cornea, the main source of refraction, then it
pass through the lens which controls 1/3 of the refraction of light
that enters the eye (the cornea, the other 2/3). Located just behind
the pupil it allows for changing of focus from distance to near
objects by altering its shape. This changing focus is called
accommodation. As a person ages the lens hardens and accommodation
becomes more difficult. Finally, the lights reach the retina that
contains photoreceptors (rods and cones) that change light into sight
by converting light into electrical impulses. These electrical
messages are sent from the retina to the brain and interpreted as
images. Simple heh?
The iris is the colored part of the eye has very fine muscles to
control the size of the pupil and thus the intensity of the light (in
conjunction with the eyelids). Being able to reduce the pupils to
slits rather than tiny circles gives the creature a greater and more
accurate control of how much light enters their eyes; this ability is
particularly important in bright sunlight. Vertical slits also have an
advantage over horizontal slits. When the creature's eyelids close at
right angles to the vertical pupil, he can reduce the amount of light
even further by bringing its eyelids closer and closer together. This
combination of the vertical slits of the pupils and the horizontal
slits of the eyelids, allows the creature to make the most delicate
adjustments of the light reaching its eye compared to any other
animal.
Also, many animals also have an additional structure called the
tapetum - a reflective layer that lies under the retina and acts as a
mirror, bouncing light back toward the retina a second time. Dogs,
cats, horses, and cattle all possess them. This allows them to
function under dim lighting better than humans. Cats, for instance,
are five times better at detecting light than humans.
This is probably the most plausible situation, while is contain
nothing new, this type of eyes has a long history of great
functionally and an acceptable field of perception. However, this type
of eyes possess only a 0.02 degree of visual range (i.e. there is only
a small point in the picture where everything is clear. As you read
this line, the paragraph above is blurred and cannot be read until you
move the focus of your eyes on it).
Eyes made from a mosaic of lens (insect-like eyes):
As opposite to the vertebrate eyes, the image is in fact many small
"independant" units that will together form the image. Each small lens
point toward a different direction and thus can view a wide angle. A
vertebrate eye has 0.02 degree of visual range (ie where objects
appear clear and sharp) but since each lens of the composite eye is
relatively large, this eye has a poor visual acuity. The image is
crude but still recognizable. However, the main reason why large
creatures do not have composite eyes, it is because this type of eyes
generally allows only a short range of vision. Flies and mosquitoes
are very near-sighted, and can see only a few millimeters in front of
them with any degree of resolution. Also, although the insect depth of
focus is very short, it is nevertheless very broad. The
near-sightedness of insects is so extreme that they see detail where
we would need a microscope to see. On the other hand, in the human
eye, the fovea, or area of sharpest focus, is only as big as our
thumb.
Vertebrates
(humans for example)
Composite eyes
(insects for example)
Each pixel is one of the several hundred lenses of the eye
As shown on the picture above, for a creature with composite eyes, the
Earth still look like the old planet we still know but the details are
poor. For an insect, the important point is probably to distinguish
the flowers from the landscape and your hand (or predator) before you
hit him. It is simple and well, it does the work for them but
seriously, any large creature would be greatly disadvantaged by this
type of eyes.
No slit at all; eyes appearing like a crystal ("crystalline" eyes)?
Think about the pernese dragons. How are they able to see something?
In fact, the best explanation is there is no retina but instead the
light receptors are distributed homogeneously in the eyes. This means
a photoreceptor near the surface can see the object far away and you
go deeper into the eyes, the photoreceptors are able to view objects
that are closer.
This would also means that the eyes are always focused no matter the
distance of the object (I admit this could seem very strange for most
of us, but imagine a photo where the close objects are as sharp and
crisp as the objects far away).
However, this do not give the same precision as a retina since the
dragon cannot have a dense quantity of receptors without blocking the
light; a dense quantity of cells would block the light for the layers
deeper in the eye (to some extant, in fact, cells are almost totally
transparent).
As said above, the advantage would be to be to always have the close
and far object focused at the same time and having a great deep
perception even with a single eye. I explain, for human and some other
creatures having a binocular vision, this is extremely useful for
evaluating deepness but if your eyes are focussed on every distance
all the time and if your brain is able to tell which signals from
which "layer" of photoreceptors, then the brain no longer need two
eyes to know the "exact" distance between the creature and an object.
This would allow the dragon to have his eyes slightly more on the side
and have a greater angle of view without sacrificing their ability to
determine deepness.
Another advantage would be to increase the angle of the eyes, bird
have their eyes on each side and human right in front. We humans with
our eyes squarely in the front of our heads, can see about 180
degrees, but we need to direct our eyes into the direction of the
object to have a clear picture. The crystalline type of eyes would be
focused not only for object of all range but also in all directions,
this means once you come into their angle of vision, it is like if the
dragon was looking directly at you all the time while we cannot
describe very well a person standing in the corner of our vision.
The main disadvantage would be their inability to have one point where
all their light receptors can be gathered. Owls for example have a
very dense retina and this allow them to see small creatures (such as
mice) even if they are very far from them. In a crystalline eye, this
situation cannot exist, they can have a good visual acuity but not as
high as the animals that are renown for their vision. Does this means
a dragon with such eyes cannot have a great vision? Absolutely not,
again, we humans have a vision angle of 180 degree and about 140
degrees of binocular overlap. Dragons with crystalline eyes could have
an angle of vision around 220 degree (i.e. the eyes slightly on the
side) and an overlaps of 110 degree. The object inside the overlapping
degrees of both eyes would greatly increase the resolution of the
object while the remaining angle of vision would be less defined (but
much better defined than the visual acuity of the corner of our eyes).
The degree where the vision of the dragon overlap would be equivalent
to the area of sharpest focus and would be obviously much greater than
our.
Glowing crystalline eyes?
Glowing eyes without slit are nonsense, I have see some trying to
explain the phenomena but their explanation contain several flaws that
make the theory highly questionable. Let face it, this is often used
to show good/bad guys in manga and other cartoon but this remains very
unrealistic. In fact, if the creature had an iris, it would be the
reflection on the iris that would give the impression of glowing eyes.
This is where the idea came from but as you all surely noticed, the
"glowing" eyes of a cat in the dark do not really glow; it is just a
reflection of the light. Now, imagine now that your pupil would glow,
you would literally blind yourself by the light emitted but also by
the reflection of this light back to you. The best example I can give
is at night when you are inside your house, if you look outside with
all the lamp turned on, the glass in the window will acts like mirror.
In other words, if you need to look outside, it is easier when there
is no light inside. Same thing for the eyes, if you have a light
source inside the eye, this would 1) blind you by activating the
photoreceptors around the light source, and 2) your own cornea would
behave like a mirror and reflect you back the light you emitted thus
blinding you even more. In a crystalline eye, the light emitted by the
"crystalline" liquid would trigger photoreceptors that are surrounding
the light source thus completely blinding the creature in the process.
All this to says, that artistically, this give dragons and fantastic
look but scientifically there is so many problems generated by this
type of eyes, that it would be a lot of trouble to gain no advantage
over the other types of eyes...
Classification and Evolution:
Many can wonder in which class the dragons can be categorized. The
dragons cannot be considerer as reptiles because they are active and
they are warm blooded, and they cannot either be mammals [because they
to the rule because it are only the mammals to lay eggs) and they do
not produce milk ] and even less be birds (because they have scales
and six members). However, the dragons have elements of each of these
classes (reptiles, birds and mammals):
Birds: hollow bones, lay eggs
Reptiles: lay eggs, have scales
Mammal: four chamber heart, specialized teeth
Unknown: six members (2 pair of legs/arms, one pair or wing)
Thus, the dragons would be categorized in their own class... It would
be a mistake to consider them in the current class because they do not
answer the physical criteria requiered to belong to one or the other.
For their evolution, I would like first to put something at light: if
you believe that the darwinism is only a theory, read this BEFORE
contacting me by electronic mail for saying that it is only theory
without good grounds.
Their evolution according to the most plausible assumption goes up
with the first primitive reptiles, when those divides to follow
different paths of evolution as to become the dinosaurs (which became
the actual birds), the mammals and other better adapt reptiles. The
dragons separate either from the dinosaurs or right before the mammal
junction which gave some kind of reptile with mammal appearance (which
look strangely close to a dragon without wings). With a few tens of a
thousand of years of evolution, some beneficial mutations could have
given them wings that have helped them to survive. This new branch in
the evolution could explain the evolution of the dragons.
Note of the author: This section is still suject to discussion.
Therefore, these informations are subject to change without notice.
Breath Weapon !?
Fire Breather:
The breath weapon of a dragon is not a magical thing that spread out
of no-where but had a more scientific explanation. When we eat our
body by digesting created a gas know as Methane (CH4), dragon unlike
human and other animal store this gas into another kind of "lung" that
will serve as a bag/canister to held the gas that will be later mixed
with a small amount of phosphor (P4) that has the propriety to ignite
in fire at the contact of air. When the dragon wants to breathe fire,
the methane is release into the lung and when the gas is in the air,
the phosphor ignites and also puts the methane in fire.
Cold/Frost Breather:
Some dragons breathe a cone of frost, the explanation for this resides
also in the food that the dragon ingests. The food is break down into
the stomach primary for nutrition but the remain bear some chemicals
reactions that will give a gas, I suppose to be Nitrogen (N2) (I have
not yet found the exact composition of it but I continue to work hard
to find the most probable natural refrigeration gas), the gas is
compress by extremely strong muscles, exactly alike the base system of
a refrigeration system, the dragon doesn't need to thing for it
because it is spontaneous and painless. When a dragon needs to freeze
an opponent, the highly compressed nitrogen, that almost reach the
liquid state, is release in the lungs and when the gas comes into air,
it uncompresses at an unimaginable speed. That result in the gas
absorbs all the heat in is environment. This cause the temperature in
without heavy heat protection are at least seriously injured and only
death remain for the weaker one.
It may have another explanation that can be explain by extremely
efficient and fast oxidation-reduction reactions but we will not
explain it much (everyone who has done is advanced inorganic chemistry
should understand the concept otherwise you should review or have
listen your college class)
Acid Breather:
The easiest of them, all organic creature secrete gastric acid to
break down the food, dragon who can spit acid have a special organ
that produce a powerful acid (probably HCl) that the dragon release
when he breathe, the opponent is burn by the acid, even with the best
armor usually make of metal that make bad reaction with acid.
For other breath weapon least know follow the same principle and don't
need much detail about them.
I made one observation during my research: it seems to have a direct
link between the breath and the food, if a dragon is starving his
breath weapon doesn't regenerate. All the incredible system of dragon
makes it the most fascinating creature in the know universe.
Reproduction
The reproductive system of these creatures is internal, it means that
at the look of their external physiognomy, it is hard (not to say
nearly impossible) to determine if this dragon is a male or a female,
only the general behavior and the small change in their color can
provide informations about the dragon's gender. Dragons lead egg like
reptiles and bird, eggs are protected by a hard shell that with time
will weaken to let the new baby dragon break it more easily. The
incubation period of these creatures is mostly unknown; some egg will
hatch in a year other two and some more than five year. The dragons
eggs are rich in calcium and I suppose that the newborn dragons eat is
shell to not waste the nutriment in it.
The mating process is known as dragon-slide: the two partners fly high
in the sky and after a moment they grab each other and close their
wing and make free-fall. Then at less than a hundred feet from the
ground they open their wing and land. The dragons so unusual mating
process is mainly because dragons love speed and risk, and add these
to the pleasure of love... you have a sensation that human could never
enjoy. (Too bad, you should have born dragon).
Society
There is currently no way to tell what kind of organization or type of
society about dragons. Legends and lores often say that dragons tend
to be loner by nature or by obligation. According to these legend,
dragons pass much of their time alone in their lair, they, during this
time, learn about their environment and how to use it wisely. Because
they are alone a great deal of time, most of them enjoy company of
other dragons and even human as long as they hadn't come in the goal
of stealing or conquest. It may be possible that dragons have some
sort of council leaded by an elderly dragon but this yet has to be
proven.
Dragons and Mankind
Throughout history dragons and human beings have been unable to live
peacefully side by side. As a result, mankind has not been able to
benefit from ancient dragon knowledge.
Man's craving for power and religious beliefs have kept Europe
engulfed in interminable and bloody struggles. The dragon lords could
not understand the reasons for man's self-destructive behavior, and
kept well out of the way, retreating to remote hiding places far from
all this confusion.
Shrouded in mystery, the dragon's trail remained lost in the obscurity
of legend.
However, the dragons secretly pursued their quest for knowledge
without completely excluding the human race, since they accepted and
taught those few men who sought the essence of truth.
We could wonder what would happen if the dragons reveal themselves to
the eyes of the humankind... Would we be able to accept another form
of intelligence probably far superior to our or would we feel the need
to fight those, who at the end, could come to our rescue, and this
under the only pretense that these beings make umbrage to us...?
Art and Jewels
The dragon is a great lover of art, especially of gold and silver, and
work, and he loves to hoard treasure. However, he is not renowned for
his love of manual work, preferring intellectual activity by far. That
is why he does not devote himself to creating jewels, but only to
"acquiring them" from human beings through various methods. Robbery,
looting, trade, barter, fraud - by any means fair or foul which
enables him to come by the jewels and precious stones he covets.
The dragon feels he never has enough jewels and he finds it difficult
to part voluntarily with a single one of his treasures. Even though,
for example, he gives jewels to the favorites in his family, he does
it purely because he knows that the young maidens cannot remove the
jewels to the outside world. He is very jealous of his belongings and
guards the treasure he has built up over the years in large
storerooms. He keeps detailed inventories of all his possessions so
that he can be alerted immediately if a single object goes missing.
Jewels serve a specific purpose for the dragon in that he usually
sleeps on a bed of gems and luxurious fabrics, such as silks and
velvets. For this bed, he never uses soft stones like pearls and
emeralds, as they are too fragile.
Another theory says that dragons also hoard "precious" items for
reasons other than just simple obsession. At a level we humans are
incapable of feeling, different metals and other items "resonate" at
certain levels, especially gold and silver. The dragons could use this
resonation to their advantage, controlling it, manipulating it. In a
nut shell, it enhanced their already remarkable "mystic" powers.
In addition to the enhancing powers, this "resonation" also had the
same addictive effect as a "rush" in humans. Hence, the more a dragon
acquired, the more he/she wanted. This also allowed their immediate
detection of any missing piece.
