No. Tenembaum discovered the slug's abilities because a man with a problem in his hand was bitten by a slug and his hand was healed. Even though your reply about the slugs coming in contact with vigors seems plausible, the ocean water would of distributed the liquid in the vigor bottles across to other marine life. So why only the slugs?
