How do sharks attract each other? ( Courtship)?

Answer 1

Not all the sharks courtships are known.
It is assumed that in general, male chases female for long distances. Female finally becomes wooed and turns upside down to copulate.
Courting basking sharks often congregate in groups of 2 or more off the West coast of the Isle of Man. Paired swimming, following nose to tail, close following, or breaching (leaping out of the water).

Answer 2

They "tumble" thru the water to attract the female. Imagine spinning around like a tornado, going in circles around a friend (only your horizontal instead of vertical). Or imagine doing a log roll in place. Not all shark species do this, and I can't remember which one(s) do(es).
Then that mean little boy shark will aim his claspers at the female and knock her up! And then leave of course.

Answer 3

im not really sure but, like whales, they have mating calls, or the male just annoys the female until she mates with him...by chasing her around or something.
