What advantage is there to extending your eyes
straight out and far away from your skull?
You can see everywhere at once except for
directly in front of your snout. Your one
blind spot is in the direction you are headed.
Your head acts like a rudder, enabling you to
pivot and twist at high speed to capture an
energy meal, like another shark or a ray.
Hammerhead's dive to extreme depths in
order to feast on a favorite, giant squid.
They hold their breath while hunting at
great depths because the icy waters passing
over their gills can dangerously lower the shark's
core body temperature.

What is it about a rain forest that attracts flamboyance?
This frog is easy pickings for a passing hawk or
nearby snake when displaying itself in full regalia.
However, by tucking its limbs under its green body
and masking its red eyes with a membrane, the frog
becomes invisible, lost in the surrounding jungle foliage.
Red-Eyes needing a mate complicates their survival.
Nature has provided a relatively few females with
an abundance of males to chose from. The date night
frenzy begins with a passing rainforest downpour.
Males everywhere hop about to dazzle the ladies.
Being chosen for mating doesn't end the competition.
Matters get ever more ugly as desperate rivals
attempt to pull the male off his bride's back,
even on their honeymoon night.

Dine with ancient reptiles that preceded the dinosaurs
by a hundred million years. Spend the day among
a thousand alligators lounging pondside in a beautiful
garden setting. What a wonderful destination for a
family picnic. Just twenty-five cents brings you the
Experience of a Lifetime!
The California Alligator Farm opened in 1907,
enduring until 1953. The farm supplemented
its income at the gate by renting alligators to
movie studios in the early days of Hollywood.

Gallop - the fastest of four gaits.
It has four beats to a cycle, one for each hoof
hitting the ground separately. Four thuds and
a silent moment when the horse's legs are
all lifted above the ground.
The Trot has a two clop gait, with two legs
striking the ground at once, then the other two
doing the same.
Cantors, the second fastest, have three clops
to their cycle. The mosey along gait is Walking.
One leg moves at a time. Each when it is
good and ready.

A three-horned dinosaur that makes its appearance
in the fossil record two million years before Earth's
catastrophic collision with an asteroid the size of
Mount Everest. The result is an immediate course
change for life on this planet. Nocturnal mammals,
small and timid, rapidly diversified to fill all the roles
once dominated by the now extinct reptiles.
Chance has given life a new path to follow.

You'll easily go through two sets of flight feathers a year.
Your first set comes just in time for the breeding season,
when you need to be at your sharpest. But as summer
closes out and the family has left the nest it is time to
replace rough, worn-out feathers with shiny and new.
Most birds lose their flight feathers one at a time
on each wing in a symmetrical pattern.
This process provides the least interference with
the bird going about its daily routine.
Waterfowl like geese and ducks, on the other hand,
lose their flight feathers all at once, leaving them
limited to paddling about the pond for the next
two to four weeks, waiting for their new feathers
to arrive.

Go back 250 million years to the Age of Dinosaurs
and you find jellyfish, not all that different from how
they appear to us today, quietly adrift. Now, go back
another 500 million years in time to discover the most
advanced and dominant animal its the day. The Earth
was mostly covered with oceans whose waters were
warmer than todays. There were many shallow seas,
thick with tropical jellyfish drifting all about.
They have no brain, no bone, no heart, no blood.
They are 98 percent jelly. Gelatinous material
capable of making decisions. They can respond
to visual threats with the speed of a mouse
running under the sofa. They manage
without a resident wizard holed up in the noggin.
Their scattered neural network diffuses responsibility
with no central authority to intervene on behalf
of the whole.
S E A S Q U I R T
What kind of biologically engineered life form preceded
the vertebrates? Crabs? Starfish? SpongeBob?
Nothing makes sense. The creature above is a tunicate,
a static filter feeder found in most any marine habitat
offering a hard surface for its anchorage. How likely
is it that this mindless, limbless, porcelain vase lookalike
would eventually lead to some dynamic, vertebrate form?
The adult sea squirt above is nothing like its
juvenile form. The larva hatching from a tunicate's
eggs looks like a tadpole from a frog pond.
A hollow nerve cord runs the animal's length,
from eyespots to powerful tail. The notochord,
a stiff but pliable precursor to the vertebra,
provides strength. This tadpole phase
lasts no more than 24 hours. The larva's mouth
cements itself to a rocklike surface once contact
is made. The animal reconfigures itself into its
unspectacular adult phase.
What is to prevent a tadpole larval type from
succeeding with this body plan? It's a winner -
sensing light, powerful tail, beginnings of a central
nervous system and vertebra. The basis for putting
on the brakes towards SpongeBob is the process called
neoteny - juvenile features replace adult characteristics
that prove less advantageous to the organism's survival.
The achievement of adult mobility delivers new
incentives for providing even greater improvements
to the animal's performance.
Winners survive.

Starfish eat mussels and clams. Starfish have no teeth.
Their food has protective shells. The starfish has five
strong arms to pry the shell open, revealing a buffet
of tasty shellfish innards. Still the starfish has nothing
to break their food into small pieces and guide these
morsels into their mouth. Crabs, spiders and insects
all have small fingerlike structures around their mouth
to provide this service. That isn't feasible for starfish
because their mouth drags the ground, likely damaging
any delicate mouth fingers.
The starfish solution is to push their stomach
out through their mouth and douse the exposed
tissue with acid. The tissue is dissolved into a
nutrient rich broth that the waiting stomach sops up.
Nature has engineered a truly out of the box
award winning solution.

You live your life heavily armored and you spend
much of your time squeezed into narrow rock crevices.
You are not king of your realm. You live to survive
another day in a nasty neighborhood. Crabs like you
come and go. They always wind up being someone's
dinner. A few breed youngsters before they go.
Some crabs among the next generation are running
around with your brand of genetics imbedded
in their being.
And isn't that what it is all about, biologically speaking?
The continuation of life. Protecting life's genetic formula.
Here is a purpose. Is it Nature's or is this merely
humanity's questioning for purpose?
Where is the bottom line?

It is a tight fit but this animal appears to have
unexpected problem solving abilities.
How does abstract planning fit into such a tiny brain?
They've had over 300 million years to refine
their mental processes. Three hundred million
generations to attack the problem anew by
constantly tweaking their genetic code.
The incentive is to always improve.
Somewhere among the many competing species
innovation always finds a place that works.

How does an octopus keep track of eight arms?
It doesn't need to. Each arm has its own sense for
touch, taste and smell as well as its own mini-brain
to call the shots once it had made sense of things.
Up to a point. Sometimes the organism needs
to be focused as an animal of one.
There is a central authority capable of overriding
dissension when a singular response is required.
Place a tightly-screwed jar containing a tasty
crab in front of a hungry octopus.
Nice try. No problem. The octopus has
crab legs for brunch. Quick cognitive reasoning.
Certainly more than instinctual, stimulus-response.
It is not a grass-munching cud chewer. They have
free time but little curiosity. An octopus has both
the free time and curiosity to be clever.
Imagine intellect among the invertebrates.

Here is a dynamic, complicated world and you can
see it only by looking through a powerful microscope.
A cell needs protection from anything that might
disrupt the intricate process of staying alive.
A membrane separates the cell from everything else.
It also determines what to let in. The various nutrients
vital to the cell's well-being are good. So are messages
from other cells. The membrane is more than a wall.
It makes decisions that require sensors for detection
and authentication of objects foreign to the cell.
Approved molecules are provided a gateway for passage.
In addition, this guardian membrane is able to
constantly update the nucleus on its status.
There are many such complex processes being
performed continuously in order to sustain life
in the cell. And what is it life employs to maintain
this operation? Molecules, dynamic and self-driven
in the performance of their task. This entire
enterprise to support life is accomplished
through the coordination of molecules in
purposeful animation.

The nucleus monitors vital aspects of the cell's status.
Something is always in need of repair. The outer wall
is always in need of replacement protein gateways.
Environmental changes may call for adjusting the cell's
metabolic rate - turn up the heat in the cold and
reduce the caloric burn when things get warm.
All this requires reliable communications between
the nucleus and the relevant cell component.
Some forms of messaging are faster than others.
Putting a protein message in a vesicle is snailmail
compared to direct messaging using the membrane.
E N D O P L A S M I C R E T I C U L U M
Here is the cell's heavy industry. The cell's proteins
are assembled by Rough ER. Spherical Ribosomes
collect on the ER's surface, passing along instructions
from the nucleus. Smooth ER synthesizes lipids,
enabling the cell to distribute energy on a convenient,
tablet form basis. They make for great storage units
and they are available in a variety of sizes.
Smooth ER also provides environmental detoxifying
much like an animal's liver.
A well-regulated ER is vital to cell welfare, so it is no
surprise to find the Endoplasmic Reticulum is in direct
contact with the nucleus membrane. You can't get
anymore immediate molecular communication
than this.
G O L G I A P P A R A T U S
Shipping and Receiving.
We get the finished proteins and lipids
from ER and prepare them for shipping.
Certain modifications first need to be made
before the actual packaging. Once the item
is packaged it is stamped with its destination
zip code, provided a vesicle for transportation,
then sent on its way.
C E L L M E M B R A N E
The cell membrane is high maintenance.
Routine exposure to outside adversity takes
its toll. Structural proteins require constant
replacement. The wall itself is made of a double
layer of fatty lipids. Each lipid molecule is bipolar,
attracted to water at one end and repulsed by it
at the other, its tail end. As a consequence, the
molecular tails always face inwards, creating an
efficient and relatively simple seal against water.

This capsule is an absolute dynamo,
providing over ninety percent of the cell's
chemical energy. It is a vital guest
to the operation because it brings its own
DNA. Mitochondria has an ancestry
separate from the rest of the cell,
yet extreme interdependence induced them
to become one and the same.
Lichen is a symbiotic relationship between
plant and animal where algae lives its life
within the confines of an animal cell.
The animal provides a protective environment
for the algae. The plant, in return, feeds the
animal through its photosynthesis of sunlight.
