Subject:       hooded seals?

I was wondering why hooded
seals are called "hooded" seals.  Do they have some form of hood on
their bodies?  If you know will you please reply. It will be greatly
appreciated, thanks!

Dear Michelle,
 Hooded seals (also called bladdernose seals, or crested seals in French) are called hooded 
because of their noses. The male hooded seals have a nasal cavity they can inflate.  When 
its not inflated it hangs down in front of the mouth.  When they inflate it it looks like a 
big hood almost as big as the head itself.  The males can also blow from one nostril 
(usually the left one) a strange looking red ballonlike sac.  During the breeding season, 
adult males chase other males away by fighting and displaying their inflated hoods and sac.
