It is kind of hard for any shark that do respect himself to walk in the malls with his fen hangs out there. This is simply impolite. He should at least hide it so a woman would not know from so far away that he is going to attack her or run after her.
Sharks got a bad habit that it eats suddenly and does not know anything about dining rules. No salt for adjusting the taste, no prayers before dining, no tissues to clean or water to swallow, nothing at all. It will not come and ask you gently, is it possible for me to eat you or should I look for another option?
Those are called in real life Wolves and not Sharks. The shark might be so wild and a bloody dude, but it is so stupid and it would attack a piece of wood thinking of it as a prey.
On the other side, wolves are mean, clever and bloody wild too. But they know when and what to attack.

Be aware of the wild wolves out there, the ones with the Dead Grey Eyes. They are the most dangerous.
