In Austin Powers
Dwarfs because of their sheer strength and laser beams attached to their heads.
Bull sharks, hammer heads, tiger and occasionaly whites
because of there fins on there heads
its because they were born that way
It is for protecting themselves.
Yes. Lots of people die from hammer head sharks . Evan other sharks
they swing there head to scare there predator
they use their hammer shaped heads to attack

No all sharks must constantly move to live
In the same way that all sharks move - by waving their tail from side to side, creating forward propulsion.
Believe it or not, more people are killed by coconuts falling on their heads than getting killed by sharks!
