Facts about Walruses
How much do you really know about the
walrus? Chances are there is plenty about them that you haven’t
heard about before. As you read these walrus facts you can be
confident that your knowledge about them is going to continue
to expand. The name of the walrus means tooth walking sea
horse.
The tusks of a full grown walrus can weight over 3 pounds
each. Each one features from 400 to 700 whiskers. From a
distance the walrus appears to be without fur. However, the
entire body is covered with a very thin layer of it. The
blubber, which is the layers of fat, on a walrus can be more
than 5 inches thick.
A walrus can remain under water for up to 30 minutes before
coming up for air. During migration they can travel up to 1,800
miles. The females tend to migrate further than the males. They
can stand very cold water that is as low as -31 degrees
Fahrenheit. When a calf is very young it will ride on the back
of its mother in the water. However, it does know how to swim
on its own. This method of movement is for protection and for
bonding.
One of the leading causes of death for the walrus is due to
various types of parasites in the water. They are able to cause
problems for the skin as well as internal infections that shut
down the normal functions of these animals. Males often kill
each other during their fight for the right to mate or in an
effort to move up the social status ladder. Females often keep
their young underneath them to prevent them from being crushed
by other adults in the area.
The skin of a walrus is very thick. This offers it
protection from the extremely cold water as well as from many
of the different predators out there. Many people are amused by
the fact that the walrus can change colors. It has to do with
their skin and their body temperatures. This is all due to the
fact that their blood vessels change in size when it is cold
versus when it is warmer. For example when it basks in the sun
the skin turns red due to the amount of blood that rushes to
the skin.
The walrus spends the cold winter months over the Bering
Sea. It is common for them to pass through the Bering Strait
during their migration patterns. One of the most amazing things
about the walrus is that they are able to sleep while they are
swimming! This is possible due to the air sacs that are located
in the throat region.
There is only one species of walrus which is quite
interesting. Most animals out there have many species so this
is a fact that helps to identify them as unique in the eyes of
researchers as well. Many people don’t realize that the walrus
molts. This occurs in June or July as they no longer need their
heavy winter coat.
When a walrus needs to break ice, it will do so by slamming
its head against it. Then it will use the tusks to make the
hole in the ice as large as it needs to. This process allows
them to have breathing holes so they can stay under water for
longer periods of time. They have to come up for air, but not
all the way to the surface. For a very long time it was unknown
how they were able to stay under water for so long. Now it is
known that they are getting air but just from another
source.
