This gang holds the belief that the Sharks are the ultimate creatures of the seas and nearly all of the sailors must submit to them. When it come down to recruiting to either increase the numbers or replace dead members as mentioned by prisoners in a quest line on Cat Island, the prisoners are starved to near death which at that point they are forced to drink shark blood for a while until they are change completely, devoted nearly all of any sense of one's self.
