many people have sent me questions wanting to know how dangerous
sharks are.
Promptly,
I would answer that meeting sharks is wonderful and a spectacle
to enjoy, or better it's a blessing. I realize that my point
of view is not impartial since I've organized a mission to meet
sharks, although I'm risking not finding any of them. (Anyhow
I've already had the opportunity to film two of them). Nevertheless
going back to the above question "Are sharks dangerous?"
I would answer as follows:
"It
depends". It depends on where, how and when we meet them
and what species we are faced with. We should take many aspects
into account but let's consider only some of them.
First of
all what kinds of sharks are we talking about? Yes, because
just mentioning the word shark is not enough. It's the same
as saying "cats" and among felines we can count both
household cats and tigers. Anyway the former can at most damage
a sofa. What is more among sharks "cats" are more
frequent than "tigers". In fact among more than 370
shark species, 80% are centimetres and not metres long. Anyway
it's true that even a shark 50 centimetres long can easily tear
to pieces a small calf.
The second
important aspect to take into account, in order to evaluate
how dangerous sharks are, is: what you are doing while the shark
is coming? You are probably on a boat, you are swimming, you
are underwater, you are fishing, chumming, maybe you can see
it or not, is it during the day or at night? Is visibility good
or the water cloudy and so on
Each of these factors intuitively
modifies the risk level.
Third: where
are you at that moment? In which expanse of sea?
It is important to know. An example? In the Bahamas by New Providence
Island it is quite easy to reach the females of the Caribbean
blue sharks (Carcharhinus perezi) while approaching the males
requires more caution because of their aggressiveness.
Fourth,
fifth, sixth, and
In
conclusion a sharks' world is complex and it is impossible to
give general answers probably because it remains so fascinating
a world!
