Sea Lion Species
Sea Lion Species Overview
There are seven known Sea Lion species
that have been identified. Sadly, one of them has already
become extinct. That would be the Japanese Sea Lion and their
end was definitely a wake up call to researchers and
conversationalists. However, they have been gone since the
1950’s and it has just been in the past decade that the best of
efforts have taken place for their survival.
The Steller Sea Lion is the largest of them all and lives in
the Northern Pacific, especially around Alaska. They were first
discovered in 1741 and the number of them continues to decline.
Researchers aren’t able to identify what is causing this drop
in numbers so they are focusing more attention on them.
Hopefully careful observation will give them the answers they
need.
The Australian Sea Lions are only found along the South
and West of this continent. There are only about 10,000 of them
left and they are protected under the National Parks and
Wildlife Act of 1972. One of the main reasons why their numbers
are low is due to the males often killing the pups. They do so
because they view them as a threat to their own dominance.
The South American Sea Lion is most often seen in the area
of Peru. They have a decent population of approximately
265,000. In fact there are indicators that the number of them
has increased along both Chile and Argentina. Their biggest
threat comes from humans because they tend to compete with
fishermen for the available food in the waters there.
The New Zealand Sea Lions are also referred to as the Hooker
Sea Lions by many people. This particular species has been
under protection since 1890. At that point it was extremely
close to extinction. Even with such efforts though the numbers
are climbing at a very slow rate. Today there are only about
18,000 of them.
The most well known is the California Sea Lion. Tourists
come from all over to see them in their natural environment.
This is one area that has gone to great lengths to help protect
the natural habitat of these animals though. These are the
types of seals you will most often see in zoos, the circus,
working with the military, and learning tricks to perform at
Sea World.
Last is the Galapagos Sea Lion which is only found on the
Galapagos Islands and Isla de la Plata. They are said to be the
most social of all Sea Lions and they are also the species with
the highest recorded numbers. They are protected by law but at
times they are threatened by various types of destructive
weather in that area.
In 2002 a very interesting mix of Sea Lion was found by
researchers. After extensive research scientists from France
verified that it was a hybrid species. These Sea Lions were a
cross between the California Sea Lion and the South American
Sea Lion. They found this mix to be one that is very
interesting. Still, we don’t know too much about them today. It
is believed that this hybrid mixing is rare so that makes it
harder to observe the offspring in depth.
Many of the different Sea Lion species are in danger of
becoming extinct. This is why so many efforts are in place out
there to help preserve their natural environment. There are
also efforts to prevent the hunting or the harming of Sea
Lions. So far such efforts have been successful but there is
still plenty more than has to be done in order for their
numbers to climb out of the danger zone.
