The blue whale is the biggest animal
known to human
beings. Even bigger than dinosaurs, blue whales are mammals
because
they are warm-blooded and they breathe through their
lungs. Every five to ten minutes, blue whales emerge
from the sea to blow out the stale air from their
lungs
through an opening on the top of their heads.
As the
air is
blown out, the water vapour that escapes is visible
at a distance as a
spray. The whales have to do this
several times to fully
clear their lungs
of the used air. Then they disappear
into the sea
again with fresh air in their lungs. For many years, the blue whale was hunted
by men
called whalers.
They wanted a special kind of bone
found in the
whale's mouth that
is light and bends easily
without breaking. This
whalebone was

of the whale was used to
make cosmetics for women and whale meat was
sold in
the market for consumption.
Today, the blue whale is practically extinct. Other
types of whales,
such as the killer whale and the gray whale, are
under special protection.
The only species of whale that seems to have
survived well is the dolphin. |
