With
fantastic grace of movement, sharks of assorted dispositions glide
silently
through practically all waters on the Earth's surface, inhabiting
seas
and oceans, bays and harbors and many inland waters and rivers.
Many
sharks are large and fearsome. In fact, one whale-like but
harmless
variety grows to about 60 feet. Conversely, there are others
that
measure only a few inches when fully matured.
Scientists
classify sharks into several hundred varieties, most are
harmless.
It is believed that only about eight varieties are dangerous
to
man.
The
most ferocious is probably the great white shark. This shark moves
swiftly
through the water and has rows of triangular teeth. It is the shark
that
usually follows ships, trailing them for long distances. Undoubtedly it
is
a man killer. Of the great white shark, Jonathan Couch, in his
History
of the Fishes of the British Islands,
wrote:
It
is to sailors the most formidable inhabitants of the sea, for
in
none besides are the powers of inflicting injury so equally combined
with
eagerness to accomplish it"
It
has long been regarded as dangerous. Pennant describing the white
shark
in 1776 wrote:
"This
grows to a very great bulk. Gillius says that in the belly of one was
found
a human corpse entire, which is far from incredible, considering
their
vast greediness after human flesh. They are the dread of all sailors
in
hot climates, where they constantly attend the ships in expectation of
what
may be dropped overboard. A man that has this misfortune
perished
without redemption. They have been seen to dart at him like
gudgeons
to a worm. ... Swimmers very often perish by them. Sometimes
they
lost an arm or a leg and sometimes were bit quite asunder, serving
but
for two morsels for this ravenous animal"
Others
reported finding a body in armour, and according to one report,
a
whole horse inside this monster.
