Seal Habitat
Seal Habitat and Distribution
You will find that seals have quite a
spread when it comes to their distribution. They can be found
from the cold regions of the Antarctic to the very warm areas
where it is extremely sunny. The majority of them are found in
the Antarctic though where it is extremely cold. They are able
to survive the low temperatures and icy conditions due to the
layers of blubber they have on their bodies.
Those that live in warmer areas don’t have as much blubber
on them because they don’t have a need for it. This is why
those that live in colder regions are heavier in size. They
will need to eat more to keep those layers of blubber on them.
This is why they are the most threatened because as their
natural habitat is affected there is less food available.
Global warming is another concern for seals. Some species
are designed to live where it is very cold. As the warmer
weather comes in they find more predators in their natural
habitat. This means they can be eaten as well as their food
supplies being shared with other animals. Those that live in
the warmer regions may find that the hotter temperatures also
reduce the cold water currents. They rely upon those cold water
currents to bring in an assortment of food to them.
Most seals live where there is plenty of salt water. They
love to dive deeply into the water in order to find the best
selection of fish. They tend to live in environments where they
won’t be disturbed by humans or by predators. They spend about
80% of their time in the water and the remaining 20% on land.
They enjoy land that has rocks and that is close to the water.
They don’t move fast or easily on land so being able to get
from the land to the water without using very much energy is
important.
Seals love to soak up the sun, even when they live in very
cold regions. This is why they will spend their time on land
during the daylight hours, then return to the water at night
after the sun goes down. You may be surprised to notice some
seals living in areas where the sandbar is low too. They will
be drawn to areas of a low tide due to the amount of food that
will be brought along with it.
It is a myth that seals migrate, and this is a common
mistake due to their relationship with whales. They can be
found moving from their natural habitat though if the
conditions are wrong there. For example when the water has been
polluted or there is a shortage of food for them to survive on.
They will continue to move until they find water that they can
feed from and a land area around it where they feel safe.
It is estimated that there are from 300,000 to 500,000 seals
in the world at this time. It is hard to get an exact number
due to their movements and the amount of time they spend in the
water. Here is a breakdown of those numbers and where those
habitats are found:
Eastern Pacific –120,000 to 150,000
Western Pacific –12,500 to 13,500
Northeastern Atlantic – 68,000 to 100,000
Western Atlantic – 90,000 to 100,000
Protecting the natural habitat of seals is very important so
make sure you find out more about it. Too much of their natural
homeland has already been destroyed by humans. We can’t expect
them to continue adapting to new environments and changing
their distribution. Humans need to learn to respect the habitat
of seals and to allow them the chance to thrive in these
locations without disruption.
