The Most Amazing Animal Migrations in the World. |
Many members of the animal kingdom
are well experienced and frequent travelers, with some extraordinarily
abilities. Thy migrate once or twice a year looking for better food
resources, and better places to mate and start a family. On their epic
trips they will cross unbelievably high distances, handle many dangers
and demonstrate talents that border on the super-natural. These are the
stories of nature's most amazing migrations:
Straw-Colored Fruit Bat |
Every
year, between October and December, about eight million straw-colored
fruit bats travel from the Congo to Zambia, the world's largest mammal
migration. The bats migrate to feed on the wild musuku fruits. The area
where they end up is so tiny that each tree ultimately holds about ten
tons of bats and the food quickly runs out.
|
Leatherback Sea Turtle |
Some
leatherback turtles have been recorded traveling across the Pacific
Ocean between Indonesia and the United States. They cover an incredible
distance of more than 12,000 miles (19,300 km) in 647 days. What's even
more impressive is the fact that each turtle knows how to find its way
back to the beach where they were born, and lay their own eggs there as
well.
|
Whale |
As
amazing as the distance covered by the Leatherback Turtles is, they are
not the record holders for longest migration. Humpback Whales travel as
far as 16,000 miles (25,700 km) annually, a much greater migrating
distance than any other mammal on Earth. They travel to warmer waters to
mate during the winter, returning to the Arctic or Antarctic parts of
the ocean for feeding in the summer.
|
Elephant Seal |
Elephant
seals travel 13,000 miles (a little less than 21,000 km) over land AND
sea every year, and they make this trip twice a year! During the first
stage of their trip males and females separate to accommodate the
different food needs for each sex, female seals eat squid, while males
eat bottom-dwelling fish. Somehow, they all reunite again and continue
their journey together.
|
Great White Shark |
Great
White Sharks travel from the California coast to the Pacific Ocean in
search of better feeding opportunities. While they travel in the open
ocean their food supply is scarce. The secret to their survival in those
times of migration are stores of fat in their livers, which can account
for up to a quarter of their weight.
|
Wildebeest |
Perhaps
the most famous animal migrators in the world, over 1.5 million
wildebeest travel from the Serengeti National Park in Tanzania to the
Maasai Mara National Reserve in Kenya. This happen between July and
October and the journey is essentially a never-ending search for food in
this harsh area. The combined number of animals traveling together
makes this one of the largest animal movements in the world.
|
Arctic Tern |
The
tiny Arctic Tern is the record holder for the longest migration route
of any animal on the planet. Each year the Arctic Terns fly an
unbelievable distance of 44,000 miles (77,800 km), from Greenland to
Antarctica, in a zigzagging pattern to ensure that they're going with
the wind current. Since they can live up to 30 years, they can travel an
astronomical 1.5 million miles (2.4 million km) throughout their
lifetime.
|
Atlantic Bluefin Tuna |
One
of the fastest swimming fish in the ocean, the Atlantic Bluefin Tuna is
known for long migrations, in short amounts of time. They cross the
entire Atlantic Ocean from the US to Japan in as little as twenty
months.
|
Monarch Butterfly |
These
delicate creatures can't survive the cold winters of the United States
and so they embark on a massive, and colorful, migration to Mexico each
year. Much like the turtles, these butterflies also know to go to the
same exact trees every year only one small detail makes this fact very
hard to believe. The journey is completed by different generations, the
butterflies that slept in the trees one year are completely different
than the ones that arrive the following year, and yet they know exactly
where to go…
|
Emperor Penguin |
Each
March, Emperor penguins strut from the coast of Antarctica to the
center of the continent. The 60 - 100 mile (100 - 130 km) trip isn't
every impressive if you look at the numbers alone, but consider the fact
that these birds don't fly, and have to waddle their way instead.
Penguins from different colonies all over Antarctica are driven by
instinct to arrive at the same place each year to breed and form new
families.
|
Caribou |
Up
to half a million of these majestic creatures travel in massive herds
for an annual journey of up to 1,600 miles (2,500 km). They travel
looking for optimal food consumption, and when they find it they can eat
up to 12 pounds (5.5 kg) of grass per day.
|
Christmas Island Red Crab |
Australia's
Christmas Island is home to around 120 million crabs that form a living
red carpet as they make their way to the ocean to lay their eggs. The
journey takes place during eighteen days in October or November each
year. The migration is dependent on the moon and the tide for optimal
conditions that will carry the crab eggs out to the sea. The migration
timing and pattern of the crabs is so accurate that many roads are
closed off for its duration.
|
Bar-Headed Goose |
Bar-headed
geese are probably the most extreme migrating animals in the world.
They have an ability to fly to incredible heights and make their way
from India to Tibet in one day. As the world's highest flying migrants,
they can pass directly over Mount Everest, which peaks at over 29,000
feet. Their high stamina means that they can not only survive, but fly
in very thin air. US humans would not even be able to breathe there
without special equipment.
