The
Emperor Penguin is most noted
for its size, reaching
up to four feet
in height, making it
the tallest
penguin of its species. Its stomach
is white
and its wings
and back
are black, lending its trademark "tuxedo look."
Although penguins
have wings they
do not fly,
but swim through
the water at an average speed of four to six miles
per hour, with possible bursts of up to twelve miles per hour. Although water mixed with cold temperatures causes humans to experience
hypothermia and even death, penguins have
a preen gland
which secretes an oil that they use to coat their feathers with so water will run off of them.
Emperor Penguins live
in the coldest region of any
other penguin on earth. They not only survive, but reproduce and
thrive where other penguins
cannot. Adult Emperor Penguins travel about sixty miles
into Antarctica
for breeding season. Although cold temperatures are a threat to the survival of other penguins and their eggs, the Emperor Penguin
has characteristics that
allow them to keep warm, notwithstanding below freezing temperatures and high winds.
After searching for a mate, the female lays a single egg
in the months of May or June. After laying the egg, the female will
carefully pass the egg to the
male to incubate until it hatches.
This process
is carefully executed so the egg does not have any contact with the ice where it would immediately die voiding the couple's attempt at reproduction that year. When the male
successfully receives the egg he incubates it above his feet in a flap of skin called a brood pouch. In order to stay warm in the extreme temperatures, Emperor Penguins form large groups and huddle together. They instinctively know when to move from the center of
this huddle toward the outer edges to give each penguin the warmth of the middle. This process allows for them to survive the brutal temperatures in the Antarctic.
After the male has the egg, the female is free to travel to get food. She returns after about two months. After her arrival she is able to regurgitate the food for the young chick when it hatches. If the chick is born before the female returns, the male is able to produce a milky substance from his esophagus to keep his young alive. When the female returns to care for her young, the male is then free to go in search of food.
While it may
seem unnatural for a species to reproduce in such extreme weather conditions, in actuality winter is the ideal season for reproduction because there is less competition for food. Emperor Penguin chicks are larger than other penguin species and an adequate
diet is essential for their survival. Only in the harsh
days of winter is there enough food for them. Emperor Penguins diet
consists mainly of cephlapods, such as octopus and squid, but they
also eat
krill and fish. Their threat for survival is not only freezing in the cold temperatures, but also natural predators such as sea lions, Orca Whales and sharks. Although global warming has raised concerns for Emperor Penguins, there is thought to be an estimated 350,000 of them in the world.
Survival in Antarctica seems impossible, yet the Emperor Penguin continues to thrive in
these freezing temperatures. Their physical characteristics, instincts and socialization allow for them to continue to reproduce and thrive in a climate that would otherwise be deadly.
