Yeah they dont hence I would swim with them
as for killing them its a joke alright
especailly since most of them are on the endangered species list.
I believe that the Chinese kill sharks to make shark fin soup, the problem being that the shark part of the dish does not actually do anything to enhance the taste; it's purely for decorative reasons.
Its the Japaneese
They catch them cut the dorsal fin off and dump teh dying shark back into the sea
Shark blood has been found to contain cancer curing agents so expect a 'few' to be caught for research purposes
