    Dear Charles Wilson,
   =20
    Some of these are pretty obscure terms, so I don't wonder that you =
had trouble finding them in your library.    I have actually never heard =
the term snorkeling used for whales.  Whales do occasionally swim just =
below the surface, so perhaps that refers to this behavior.
   =20
    Sailing:  I have heard this term used to describe a behavior of =
right whales.  They sometimes hang vertically in the water with their =
flukes above the surface and 'sail' around.  We don't know why they do =
this.  It could be their version of wind surfing.
   =20
    Laminate:  I think the term you really mean is laminae, the term for =
growth rings found on whales' ear bones and teeth.  Scientists count =
these rings to determine the age of the whale.  Teeth provide the best =
indicator of age, although teeth in older individuals have worn down so =
some information is lost.    Since baleen whales do not have teeth, =
scientists needed to find another way to age them.  The ear plug =
(technically known as the tympannic bullae) also provides them with =
laminae to count.  While teeth can be extracted from a live animal, ear =
plugs can only be obtained after the whale is dead.
   =20
    Saddle patches:  Saddle patches are patterns of lighter pigmentation =
behind the dorsal fin on killer whales.  Scientists use the shapes of =
saddle patches and variations in the shape of dorsal fins to identify =
individual killer whales and track them throughout their lives.

    I hope this information answers your questions and you obtain your =
whale watcher award.

    Best Wishes,
